There is an amendment to our Constitution which prohibits the Government from infringing on our God given right to keep and bear firearms or whatever other form of protection from tyranny as we so choose.
Just clarifying a bit.
Point taken.
There is no constitutional legislative power to deny individual firearm ownership.
I would also point out that there is no Article I, Section 8 power authorizing the general government to ban any firearm (or infringe the right to keep and bear arms in any way).
The anti-Federalists were afraid that the Bill of Rights would be misunderstood as prohibiting actions which the general government has no power to do. And that by repealing the BoR (or any of its articles), this would be understood as "authorzing" the government to infringe our rights.
Repealing the 2nd Amendment doesn't authorize the government to ban firearms. The only thing that protects our right to keep and bear arms is our willingness to use them, if any tyrant should try to disarm us.
Just as there is no constitutional right to free speech. These rights are inherent in free people.
In the 1886 Presser case, SCOTUS agreed with you. Even if there was no second amendment, the states could not infringe the right to keep and bear arms.
Over time, the courts have bastardized and gutted the constitution, so that it's form in practice is utter subversion of its form in principle.
