No, your understanding is faulty. The first part of the second amendment is the most important part.
In the Constitution, "militia" was a term of art that referred generally to an armed population. I was referring to the population when called into national service via Article I Section 8 Clause 16. Hunter Biden can own a gun via the second amendment, but nobody would think him qualified to be called up for national service.
"Being necessary to the security of a free state" is why the second amendment was so important. The Framers feared a standing army that could be used by a tyrant against the states, or that larger states might take over smaller states, so they expected other states to band together in defense of the "aggrieved state. This is also the basis for Article I Section 10 "or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay" and Article IV Section 4 clause "and shall protect each of them against Invasion."

In Federalist #8, Alexander Hamilton was afraid that each state would raise its own army to defend against neighboring states:
The institutions chiefly alluded to are STANDING ARMIES and the correspondent appendages of military establishments. Standing armies, it is said, are not provided against in the new Constitution; and it is therefore inferred that they may exist under it. Their existence, however, from the very terms of the proposition, is, at most, problematical and uncertain. But standing armies, it may be replied, must inevitably result from a dissolution of the Confederacy. Frequent war and constant apprehension, which require a state of as constant preparation, will infallibly produce them. The weaker States or confederacies would first have recourse to them, to put themselves upon an equality with their more potent neighbors. They would endeavor to supply the inferiority of population and resources by a more regular and effective system of defense, by disciplined troops, and by fortifications. They would, at the same time, be necessitated to strengthen the executive arm of government, in doing which their constitutions would acquire a progressive direction toward monarchy. It is of the nature of war to increase the executive at the expense of the legislative authority.The expedients which have been mentioned would soon give the States or confederacies that made use of them a superiority over their neighbors. Small states, or states of less natural strength, under vigorous governments, and with the assistance of disciplined armies, have often triumphed over large states, or states of greater natural strength, which have been destitute of these advantages. Neither the pride nor the safety of the more important States or confederacies would permit them long to submit to this mortifying and adventitious superiority. They would quickly resort to means similar to those by which it had been effected, to reinstate themselves in their lost pre-eminence. Thus, we should, in a little time, see established in every part of this country the same engines of despotism which have been the scourge of the Old World. This, at least, would be the natural course of things; and our reasonings will be the more likely to be just, in proportion as they are accommodated to this standard.
In Federalist #29, Alexander Hamilton argues that a militia of an armed populace is a counter-force to standing armies:
If a well-regulated militia be the most natural defense of a free country, it ought certainly to be under the regulation and at the disposal of that body which is constituted the guardian of the national security. If standing armies are dangerous to liberty, an efficacious power over the militia, in the body to whose care the protection of the State is committed, ought, as far as possible, to take away the inducement and the pretext to such unfriendly institutions...James Madison, Federalist #46:"The project of disciplining all the militia of the United States is as futile as it would be injurious, if it were capable of being carried into execution. A tolerable expertness in military movements is a business that requires time and practice. It is not a day, or even a week, that will suffice for the attainment of it. To oblige the great body of the yeomanry, and of the other classes of the citizens, to be under arms for the purpose of going through military exercises and evolutions, as often as might be necessary to acquire the degree of perfection which would entitle them to the character of a well-regulated militia, would be a real grievance to the people, and a serious public inconvenience and loss. It would form an annual deduction from the productive labor of the country, to an amount which, calculating upon the present numbers of the people, would not fall far short of the whole expense of the civil establishments of all the States. To attempt a thing which would abridge the mass of labor and industry to so considerable an extent, would be unwise: and the experiment, if made, could not succeed, because it would not long be endured. Little more can reasonably be aimed at, with respect to the people at large, than to have them properly armed and equipped; and in order to see that this be not neglected, it will be necessary to assemble them once or twice in the course of a year.
But though the scheme of disciplining the whole nation must be abandoned as mischievous or impracticable; yet it is a matter of the utmost importance that a well-digested plan should, as soon as possible, be adopted for the proper establishment of the militia. The attention of the government ought particularly to be directed to the formation of a select corps of moderate extent, upon such principles as will really fit them for service in case of need. By thus circumscribing the plan, it will be possible to have an excellent body of well-trained militia, ready to take the field whenever the defense of the State shall require it. This will not only lessen the call for military establishments, but if circumstances should at any time oblige the government to form an army of any magnitude that army can never be formidable to the liberties of the people while there is a large body of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready to defend their own rights and those of their fellow-citizens. This appears to me the only substitute that can be devised for a standing army, and the best possible security against it, if it should exist...
Where in the name of common-sense, are our fears to end if we may not trust our sons, our brothers, our neighbors, our fellow-citizens? What shadow of danger can there be from men who are daily mingling with the rest of their countrymen and who participate with them in the same feelings, sentiments, habits and interests?
But ambitious encroachments of the federal government, on the authority of the State governments, would not excite the opposition of a single State, or of a few States only. They would be signals of general alarm. Every government would espouse the common cause. A correspondence would be opened. Plans of resistance would be concerted. One spirit would animate and conduct the whole...That the people and the States should, for a sufficient period of time, elect an uninterupted succession of men ready to betray both; that the traitors should, throughout this period, uniformly and systematically pursue some fixed plan for the extension of the military establishment; that the governments and the people of the States should silently and patiently behold the gathering storm, and continue to supply the materials, until it should be prepared to burst on their own heads, must appear to every one more like the incoherent dreams of a delirious jealousy, or the misjudged exaggerations of a counterfeit zeal, than like the sober apprehensions of genuine patriotism...
Extravagant as the supposition is, let it however be made. Let a regular army, fully equal to the resources of the country, be formed; and let it be entirely at the devotion of the federal government; still it would not be going too far to say, that the State governments, with the people on their side, would be able to repel the danger...
To these would be opposed a militia amounting to near half a million of citizens with arms in their hands, officered by men chosen from among themselves, fighting for their common liberties...
Besides the advantage of being armed, which the Americans possess over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition, more insurmountable than any which a simple government of any form can admit of...
Let us not insult the free and gallant citizens of America with the suspicion, that they would be less able to defend the rights of which they would be in actual possession, than the debased subjects of arbitrary power would be to rescue theirs from the hands of their oppressors. Let us rather no longer insult them with the supposition that they can ever reduce themselves to the necessity of making the experiment, by a blind and tame submission to the long train of insidious measures which must precede and produce it.
The republican form of government and protection from invasion was for the fear of larger states invading smaller states and expecting neighboring states to band together to repel the invasion. It had nothing to do with the federal government protecting the border; the states were expected to protect each other's borders.
From Federalist #43 (James Madison):
6. "To guarantee to every State in the Union a republican form of government; to protect each of them against invasion; and on application of the legislature, or of the executive (when the legislature cannot be convened), against domestic violence.In a confederacy founded on republican principles, and composed of republican members, the superintending government ought clearly to possess authority to defend the system against aristocratic or monarchial innovations. The more intimate the nature of such a union may be, the greater interest have the members in the political institutions of each other; and the greater right to insist that the forms of government under which the compact was entered into should be SUBSTANTIALLY maintained. But a right implies a remedy; and where else could the remedy be deposited, than where it is deposited by the Constitution?
Madison sets up the argument by pointing out that the several states are of like disposition. A "superintending government" (the federal government, in this case) is the natural home for the authority to defend the system (republicanism). The more alike the states are, the more interested the states will become in each other's affairs, and the more desirable it will be for each state to maintain its form of government in harmony with the others.
Madison then gives a brief history lesson of past confederacies of dissimilar city-states.
Governments of dissimilar principles and forms have been found less adapted to a federal coalition of any sort, than those of a kindred nature. "As the confederate republic of Germany,'' says Montesquieu, "consists of free cities and petty states, subject to different princes, experience shows us that it is more imperfect than that of Holland and Switzerland. '' "Greece was undone,'' he adds, "as soon as the king of Macedon obtained a seat among the Amphictyons.'' In the latter case, no doubt, the disproportionate force, as well as the monarchical form, of the new confederate, had its share of influence on the events. It may possibly be asked, what need there could be of such a precaution, and whether it may not become a pretext for alterations in the State governments, without the concurrence of the States themselves.
Madison goes on to say that the federal government is not expected to enforce republicanism onto the states, it is enough to simply "guaranty" to the states a republican form of government, and the states will take care of enforcing it on each other.
These questions admit of ready answers. If the interposition of the general government should not be needed, the provision for such an event will be a harmless superfluity only in the Constitution. But who can say what experiments may be produced by the caprice of particular States, by the ambition of enterprising leaders, or by the intrigues and influence of foreign powers? To the second question it may be answered, that if the general government should interpose by virtue of this constitutional authority, it will be, of course, bound to pursue the authority.But the authority extends no further than to a GUARANTY of a republican form of government, which supposes a pre-existing government of the form which is to be guaranteed. As long, therefore, as the existing republican forms are continued by the States, they are guaranteed by the federal Constitution. Whenever the States may choose to substitute other republican forms, they have a right to do so, and to claim the federal guaranty for the latter. The only restriction imposed on them is, that they shall not exchange republican for antirepublican Constitutions; a restriction which, it is presumed, will hardly be considered as a grievance.
This is how Madison disposes of the word "guarantee" in Article IV -- it is limited to the federal government issuing the guaranty to the states, but not enforcing it onto the states from above. The states were expected to police themselves based on their mutual common alignments, unlike how the "free cities and petty states, subject to different princes" of Europe behaved.
Regarding invasion, Madison expresses the fear that larger states will invade smaller states, but the other states will intervene to keep the peace.
A protection against invasion is due from every society to the parts composing it. The latitude of the expression here used seems to secure each State, not only against foreign hostility, but against ambitious or vindictive enterprises of its more powerful neighbors. The history, both of ancient and modern confederacies, proves that the weaker members of the union ought not to be insensible to the policy of this article. Protection against domestic violence is added with equal propriety. It has been remarked, that even among the Swiss cantons, which, properly speaking, are not under one government, provision is made for this object; and the history of that league informs us that mutual aid is frequently claimed and afforded;
Regarding insurrection, Madison writes that the federal government must support the state governments to quell insurrections because the federal and state constitutions are too interwoven to let domestic violence go unchecked. Madison thinks that the threat of federal involvement is sufficient to prevent an insurrection from starting.:
Why may not illicit combinations, for purposes of violence, be formed as well by a majority of a State, especially a small State as by a majority of a county, or a district of the same State; and if the authority of the State ought, in the latter case, to protect the local magistracy, ought not the federal authority, in the former, to support the State authority? Besides, there are certain parts of the State constitutions which are so interwoven with the federal Constitution, that a violent blow cannot be given to the one without communicating the wound to the other. Insurrections in a State will rarely induce a federal interposition, unless the number concerned in them bear some proportion to the friends of government. It will be much better that the violence in such cases should be repressed by the superintending power, than that the majority should be left to maintain their cause by a bloody and obstinate contest. The existence of a right to interpose, will generally prevent the necessity of exerting it.
Madison writes about the fear of foreign influence in a state (an invasion of aliens) fomenting violence amongst the citizens, but that the remedy is the federal government organizing the neutral states to intervene on behalf of the rest of the nation.
...May not the minor party possess such a superiority of pecuniary resources, of military talents and experience, or of secret succors from foreign powers, as will render it superior also in an appeal to the sword? May not a more compact and advantageous position turn the scale on the same side, against a superior number so situated as to be less capable of a prompt and collected exertion of its strength? Nothing can be more chimerical than to imagine that in a trial of actual force, victory may be calculated by the rules which prevail in a census of the inhabitants, or which determine the event of an election! May it not happen, in fine, that the minority of CITIZENS may become a majority of PERSONS, by the accession of alien residents, of a casual concourse of adventurers, or of those whom the constitution of the State has not admitted to the rights of suffrage? I take no notice of an unhappy species of population abounding in some of the States, who, during the calm of regular government, are sunk below the level of men; but who, in the tempestuous scenes of civil violence, may emerge into the human character, and give a superiority of strength to any party with which they may associate themselves. In cases where it may be doubtful on which side justice lies, what better umpires could be desired by two violent factions, flying to arms, and tearing a State to pieces, than the representatives of confederate States, not heated by the local flame? To the impartiality of judges, they would unite the affection of friends...and that it is a sufficient recommendation of the federal Constitution, that it diminishes the risk of a calamity for which no possible constitution can provide a cure. Among the advantages of a confederate republic enumerated by Montesquieu, an important one is, "that should a popular insurrection happen in one of the States, the others are able to quell it. Should abuses creep into one part, they are reformed by those that remain sound."
We have to understand that the Framers were less concerned about foreign invasion than they were about one state invading another state. Madison discusses protection from invasion and protection from domestic violence as the same issue from a federal perspective.
...the history of [the Swiss cantons] informs us that mutual aid is frequently claimed and afforded...Why may not illicit combinations, for purposes of violence, be formed as well by a majority of a State, especially a small State as by a majority of a county, or a district of the same State...
there are certain parts of the State constitutions which are so interwoven with the federal Constitution, that a violent blow cannot be given to the one without communicating the wound to the other.
Insurrections in a State will rarely induce a federal interposition, unless the number concerned in them bear some proportion to the friends of government.
It will be much better that the violence in such cases should be repressed by the superintending power, than that the majority should be left to maintain their cause by a bloody and obstinate contest.
Madison then suggests that it is the neighboring states that should be the active bodies that quell domestic violence, not the federal government.
In cases where it may be doubtful on which side justice lies, what better umpires could be desired by two violent factions, flying to arms, and tearing a State to pieces, than the representatives of confederate States, not heated by the local flame? To the impartiality of judges, they would unite the affection of friends.
Finally, Madison summarizes the entirety of Federalist #43 with this plea to the states: that the obligations between states is more than just legislative ratification of a compact between states (like the Articles of Confederation). The several states can no longer take a breach of the Articles as an excuse to break the compact. the time has come to put effort into keeping the compact intact by mutually working to protect it.
PERHAPS, also, an answer may be found without searching beyond the principles of the compact itself. It has been heretofore noted among the defects of the Confederation, that in many of the States it had received no higher sanction than a mere legislative ratification. The principle of reciprocality seems to require that its obligation on the other States should be reduced to the same standard. A compact between independent sovereigns, founded on ordinary acts of legislative authority, can pretend to no higher validity than a league or treaty between the parties. It is an established doctrine on the subject of treaties, that all the articles are mutually conditions of each other; that a breach of any one article is a breach of the whole treaty; and that a breach, committed by either of the parties, absolves the others, and authorizes them, if they please, to pronounce the compact violated and void. Should it unhappily be necessary to appeal to these delicate truths for a justification for dispensing with the consent of particular States to a dissolution of the federal pact, will not the complaining parties find it a difficult task to answer the MULTIPLIED and IMPORTANT infractions with which they may be confronted? The time has been when it was incumbent on us all to veil the ideas which this paragraph exhibits. The scene is now changed, and with it the part which the same motives dictate.
Madison's point to Article IV Section 4 is this: The federal government doesn't have to act directly, it can empower the states to mutually act on its behalf to protect against invasion. This was the expected intent of the federal government. Things have become so twisted that the federal government is now DEMANDING that states stand down while it refuses to act, when it was the Framers' intent that the states would act on behalf of the federal government to protect against invasion, externally or internally because of an armed populace.

Wrong. A prefatory clause gives an example of why the operative clause is true. It could just as easily read, "Carrots are required for good health, the Right of the people to keep and bear arms shall not be infringed" and still be both grammatically and logically true.
Everything else in your screed is an often used attempt to tie RKBA to militia service. This is backwards. We need the Right because it makes forming a citizen militia easier, however the Right is not predicated on suitability for militia service alone.
