You used the word "framers" to describe who wrote the Constitution. Well, these men viewed standing armies with a jaundiced eye, as the enemy of liberty. Thus state militias were seen as necessary to secure the state, as in loyal to the federal government created by the Constitution. 

I appreciate this idea and would love to see the military industrial complex destroyed and have state militia replace the killing machine that allegedly defends us from unwashed masses who happen to live above sand holding valuable resources American corporations need for easy profits. 

As far as individual rights, I support them and demand individual responsibility. Make ownership legal across the board including fully automatic rifles, license and insure these weapons.  With liability coverage and bullet tracking, owners will necessarily protect their arsenal from theft and unauthorized use.
