Hey Moonshadow, I'm glad you're back. I wonder do you have the time to answer this question?
@Moonshadow: I'm still waiting for your non-arbitrary definition of "acceptable weaponry", and if it's not a simple static list then please outline the valid circumstances for a few representative weapons. If it's truly non-arbitrary, then I'm sure myself, FirstAscent, Ayeyo, Hawker *and* bitcoin2cash, Rassah, FredericBastiat will all instantly realise that the definition cannot logically be otherwise - or at least, we will after some (finite) debate.
Okay, I'll try to define it, as I see it. Basicly, a device that has
no other legitimate use beyond mass destruction is verboten. This is because, if it has a legitimate use, then we have no right to prohibit or even substantially burden that legitimate use. This, of course, means that WMD of any form are out. Nuclear
weapons fall into this catagory, but nuclear fuels do not. Yet, this applies to governments as well as citizens; for it is citizens that actually run governments. People are fallible, and if a citizen cannot be trusted to own such a weapon (due to it's enourmous threat potential) then no one can be rationally trusted to have command control over a government's arsenal either.
Back on topic, if your neighbor has a history of mental illness or a strong propensity towards violence; it is within the right of the community to collectively choose to restrict that neighbor's property rights
so long as he continues to choose to live within the community. This is why one would have to go to a court. This is a form of government, but it's community specific. If you don't like the community's restrictions, move. As I see it, the individial should have the right to own a certain class of weapons without asking for permission from either the government or the community (so long as he has no history of misbehavior). This class of weapons, in my view, can reasonablely be limited to weapons that can be borne (held and operated) by a single person, are sufficiently accurate (in practiced hands) as to no be a realistic threat to bystanders simply by reason of their presence. I.E. an "assault" rifle; be it semi-auto, burstable or automatic, should qualify because in the right hands it is a very precise weapon. However, a grenade launcher would justify a
review by the community (or government, if you prefer) because, even though it can be borne by a single person, it is not possible to be a precise weapon when in use. It is quite plausible to hit one's target (or attacker) in as precise a manner as the weapon allows and still cause great harm or death to bystanders. Likewise, although a machine gun designed to be "crew served" and thus it is not reasonablely possible to be born by a singe individual, can be very accurate; it still might justify review because it's not possible for a single person to be responsible for the results of the weapon being utilized. A fictional description would be the 'sentry gun' in TF2.
There is a bit of a disconnect here that has not been well addressed. I'm a true libertarian, and hit the max position on every one of those 2D political quizes, but the question that is never asked is "should government exist?". I am not a anarchist, although I can agree that from a philisophical perspective that anarchy is the logical end conclusion, taken to it's extreme. But most libertarians are not anarchists, even though many here seem to be.
