My philosophical answer: YES! -- But with a few caveats... We have to see where the limits of the premise fail to make sense.

Let's say I discovered my next door neighbor exercised their 2A Right to secure a 'NBC' weapon. I would argue that if my neighbor also were inclined to talk about how proud he would be if his children were to sacrifice themselves in jihad... I would then feel perfectly justified, sending MY agents onto their property on a mission to prosecute their 'liberty' (with extreme prejudice). In other words, if I can't trust them with some 'unlimited' category of arms, I'd have to kill them.

Would I opt for the 1st strike if I learned they had acquired say a 50cal BMG? Probably not. But if he came onto my property brandishing even a little Springfield in a threatining manner, I'd deploy my Claymores in one of the various killzones protecting my perimeter.

However, since my neighbors are good people and I don't think about betrayals and no heightened state of alarm exists along our fence(line aka border).

And since we don't live in an arid climate, I've never even considered the restorative effort required if he decided to sow salt.

Any weapon is an interesting way to frame the question. Should a person who can afford to and, is able to procure such a weapon, capable for instance of destroying the earth (hypothetically of course) be allowed to own that weapon? Of course the answer should be a resounding NO!

The argument if framed around the venerable 2nd Amendment leaves a certain amount of leeway however reasonable people would push back hard on extremes, especially in light of the concept of the 2nd amendment when put forward after the revolution.

Weapons that a well regulated, civilian militia were "REQUIRED" to have and maintain were limited to the type of firearm (musket - rifled perhaps), so many rounds of ammunition and other goods required to keep a militiaman in the field for a period of time.

This, I believe limits the 2nd amendment to something that is "reasonable" and would preclude many weapons that would not fit that particular model. It is not carte blanche' license to own and use any weapon that one feels compelled to acquire.

Hell no. If fully automatic weapons were easily available no doubt the bad guys would have them.
How about owning grenade launchers so if you live isolated and your dogs start barking you could fire away to deter or kill the intruder they would also be picked up by the bad guys.
i do believe that there are enough legal weapons that can be purchased that can be used by us private citizens for self defense at this time.
As an aside I personally would like to own a grenade launcher but it will never be.
