Let me try something here:
Check this figure ground pix:
Most folks look at this and see a cup of sorts. They will see the cup no matter how many times they look at the picture.
Look at it long enough, and you can see two heads facing each other.
Some folks can only see the two heads. Some can see the two heads and can also see the cup at will.
My last reply was a verbal figure ground. Let's say that 'shall not be infringed' is the cup.
Then let's say that "the right of the people" are the two faces.
The Second Amendment is a verbal figure ground, for it also has two aspects. One aspect is an injunction against government not to get involved in infringing a particular right of the people.
The other aspect is the government's recognition and acknowledgement that the people had and have the pre-existing right to own and bear arms.
Some folks read the amendment and see only an injunction against government not to infringe on something.
They never see the 'faces' -- the fact that the people have the right to keep and bear arms.
Both aspects of the picture are present in the Second Amendment. One, the injunction against government; Two, acknowledgement and recognition of the people's pre-existing right to keep and bear arms.
Of course, the Founders already knew that, but they thought it wise to put it in writing lest future despots attempt to pursuade the people that the right to keep and bear arms is something that the government, either federal or state (by virtue of Article VI) controls.
But even if the Second Amendment were not written, the law of survival is supreme over all laws.
