How can the courts take away a GOD given RIGHT? If it can be taken from you, then it's only a Privilege to be administered has the courts or the Politicians see fit.
That would make the 2nd Amendment an absolute right. If you look carefully you will find no such thing in the BOR. What you are saying would give a felon the right to be armed while serving his term in jail. I don't see that as rational. If you look at colonial and early republican practice you will see how this was interpreted at the founding - I would be happy enough to get back to that (with the exception that native americans, women and blacks were citzens ;) ).
Your RKBA is a fundamental right (some call it a natural right) which is regulated by your state when you become a member of society and are then protected and governed by those laws.
You want to be a mountain man, separate from society, governed by the laws of nature, fine. You have the right to defend yourself however you wish.
But, once you become part of a society, a citizen of a state, you are governed by those laws.
