And Supreme Courts can't be biased, lobbied, or manipulated into making decisions that seem to defy common sense? If your argument is, "Well, that's the way our system works. Just have to deal with it and respect it." Fair enough, I suppose, but I don't impart infallibility to the Supreme Court.
I don't think referencing weapons other than small arms to explore arbitrary interpretations and applications of the 2nd amendment is a strawman. Going by the words at face value, you should be permitted to own a nuclear weapon. Like I said, the framers didn't futureproof it nor make a distinction between muskets and cannons. We don't allow citizens to own bombs because it makes sense. Ultimate point though is that the well regulated militia phrase does exist and seems to be willfully ignored or at the very least loosely interpreted.
