"People" is made up of individuals. A "Militia" may be necessary, but the people (and each person) retains the right to keep and bear arms.
You are a fool to tie it to the Militia. It was a preexisting individual right. The 2A take authority away from the Federal Government.
There are no individual terms used in our Second Amendment. And, the People are the Militia. There is no such Thing as well regulated militia of Individuals under our Constitutional form of Government.
