I think that in case you might need to defend yourself against the municipal level too sometimes, not only federal. I think the way to do is to not make it illegal to own a gun, but, if you want to buy or sell, or to mass produce, then you need a license (but it should not be banned entirely), and you also need mandatory training (but only once, not every month or year) to purchase a gun. Also, I think that it should be preferred (but not mandatory) to use weapons and defenses other than a gun. You can fight by hand, arrows, sword, staff, stones, gardening tools, sharpening the edges of DVDs and throwing them, etc (or, if you are a pacifist, then you do not have to fight at all). So, having a gun should be discouraged, but it should not actually prevent you to have one if you wish. (If the weapon emits excessive amounts of ionizing radiation, then it would be banned, though.) And, military service should never be required. (Requiring training to purchase a gun is good, but it should be only once; otherwise the law becomes too obstructive.) Guns should not be mandatory either; some people don't like guns. (Apparently in one place, it is mandatory to own a gun unless you don't like guns, or cannot afford it, or any of a number of other exceptions. So, such law is not obstructive, and if it is shown to help, then it should be kept, but if it makes it worse, then it should be discarded.) I live in Canada, and I think the law is that when transporting guns they must be unloaded, and that seem good to me (although the law as implementation may be a bit too strict), and once the police department said that anyone who has a gun but doesn't want it can voluntarily give to them, and I think that is OK too.
