You are side-stepping the issue that you red-herringed around. Most people in the US who own a gun do for personal or home defense. So the question is, do you think those reasons should be on the list you are advocating for?
No. I'm not red herringing at all. The right to lethal self-defense with a gun is functionally equivalent to the right to kill at will.
Here is the problem with your argument. If you think self- and home defense should not be on the list, then you are opposed to people being able to effectively defend themselves and their families against lethal force or grave bodily harm. If you think those reasons should be on the list, then the list is pointless, because anybody who wanted to own a gun for nefarious reasons would simply just check that box.
As should be clear, "self-defense" is
not among the valid reasons for owning a firearm in Australia, or as far as I know anywhere else other than the United States. Americans only think they need a gun for self-defense
because the people they are defending against also have guns. Any gangbanger can hand over a benjamin in a Detroit back alley and get a gun because America is absolutely awash with guns. You are
forced to make the assumption that any potential lawbreaker will have a gun, and that they always have lethal intent. And you carry for self-defense, so you shoot them. Preemptively if you can. Oops, made a mistake? Too late. That guy reaching for his wallet is dead and you've made his children fatherless. Small price to pay for Freedom, though, right?
This is why another part of Arthwollipot's Great American Gun Plan involves massively reducing the number of guns in circulation - by confiscating and destroying guns that are used in crimes, by heavily restricting the manufacture and sale of new guns, and by reducing the reach of the black market. Yes, determined criminals will still be able to get guns, as still happens here. But they will be far less common and there will be no need to assume that any random jerk rolling the local 7-11 will be in possession of a handgun.
When you cite "self-defense" as the reason for owning a gun, you are making the assumption that you
will be attacked with lethal force. I never have been. Is daily life so randomly violent where you are in America that you feel that you have to be capable of lethal self-defence at all times? I would expect that of Somalia and South Sudan, but the United States purports to be a developed nation.
No, "self-defense" is not a valid reason listed in the firearms legislation in Australia, and somehow we're not all being raped and murdered because of it. Because believe it or not, the rule of law for the most part actually works here, and we don't need to all become vigilantes and take crime prevention into our own hands. Australia's a pretty nice place, actually. You should come visit some time and see what this so-called "woke fascist nanny state" is really like.
