That during time of war we'd show up armed to help defend our Country? Now who's drinking the bong water? How are we supposed to show up armed if we don't have an INDIVIDUAL Right to keep and Bear arms?
Yeah... Thomas Jefferson would kick you in the teeth for your silly assertions.
That's one of the enumerated powers. It's not a voluntary sort of thing. They call, you go.
BTW, it has been common in the Western World for probably 4,000 years for communities to maintain armories where they kept "special weapons" and "armor" and other instruments of war ~ e.g. chariots (with harness), larger crew served weapons, battering rams, etc.
I suppose you could have "individual ownership" of such devices, but you'd have to be much wealthier than the average guy living in a wattle and daub hut to keep it in out of the weather when not in use.
You can't deny the right of a community as a whole to own weapons ~ and of course individuals have a God given right to own weapons, but not everything in matters of war depends on you owning your own weapon ~ own a tank ~ now, drive that sucker out of your front yard, and lo and behold you find the soil in your area isn't firm enough to hold it up and your tank will be in a ditch of its own making.
Or, bring your own jet takeoff field so we can have use of your fighter craft to deend against the common enemy.
