Well sure, reasonable is good. Maybe you can illuminate me - are there any absolute rights outlined as being recognized by the USC? I do not believe that any are absolute, but then I am not certain legally if there may be an exception.
And if there are no absolute rights, then the 2nd must also be recognized as being non-absolute.
There is an argument used by gun control proponents which has been termed the “nuclear strawman”. This says “since arms is not clearly defined, what prevents an individual from claiming that they need to have a nuclear weapon as an arm?” It’s sort of silly from one standpoint, but then again…there isn’t really a concrete, absolute ruling on the limitations of the term “arms”. I mean on a Constitutional basis, yes? This may sound like a spurious argument, but I am being serious - has the USC ever ruled that there was no Constitutional “Right” to have nuclear weapons, or weapons of mass destruction? Yes, they sort of did in Miller, I’m gathering, with their bit on what the militia would use. But (and please correct me, maybe I’m not quoting you properly), I think what you said earlier is that if Miller had gone the other way, only that specific portion of the NFA would have been over-ruled.
What I’m getting at is - of course, it is silly (IMO) to think that private individuals can and should employ or keep fully-functioning clearly military arms, such as nukes, M1A’s, Harrier Jump Jets, or Aircraft Carriers.
But unless and until the SC rules a bit more clearly, I think there seems to be a lack of clarity in there. And part of the basis for that is the lack of clarity on collective versus individual intent.
And another thing that comes up too, but gets somewhat pushed aside - the 2nd Amendment is not just about guns. Yes, we’ve mentioned nukes, but on the other side of the extreme - the 2nd Amendment, in my view, was intended to recognize a right to have knives, shuriken, baseball bats, clubs, and - and here is where a lot of people may disagree with me - fists.
There is a large amount of text written by the founding fathers on the basis of the common man keeping weapons as a defence against tyranny, both locally and from abroad. But I keep finding serious implications and explicit terms that seem to say that the 2nd 's purpose may also be deeper - that of the right of protecting your individual life, and of self-defense. But I do not know. 
It would be interesting to be able to prove that the right to “personal self defense” is recognized by the terms and (equally importantly?) by the intent of the writers. It’s something I have been thinking about much lately.
I would love to put in web-format all of the research I’ve done and why I came to the conclusions that I have, but I don’t have time right now. However, since this issue shows no sign of going away in this Century, I suppose I do have some leeway…
