@wesdym I think there's still a case to be made that a well-armed population might, in extreme circumstances, serve as a last line of defense (look at the situation in Ukraine, for example).
So in that sense, it does still sere a purpose to the state in that it provides a little bit of extra safety in the case of a very unlikely event.
My main point, though, is that for this purpose, it is more than enough to allow a citizen to keep a rifle in a safe and only take it out to use it for practice in dedicated places.
In other words, *if* you subscribe to the common interpretation that the US constitution protects the right to bear arms in case of federal over-reach, then you still can't derive from that a right to carry a firearm, which many pro-gun people often defend because "constitutional right".
