Absolutely incorrect. No individual, including those collectively calling themselves the government, is justified in coercive agression against another unless acting in self-defense. The axiom makes no mention of vague notions such as the 'social good'.
Sorry if you feel I have misinterpreted this point - perhaps I have. But the way I see it, one has a choice between two 'coercive influences' - the coercive influence of the state in banning the widespread possession of firearms, or the coercive influence of people
using those firearms. I guess it comes down to a 'lesser of two evils' situation for me.
Secondly, who the fuck am I, or anyone else to tell other people they are not allowed to possess a gun?
If I may address this point more fully, there are a couple of problems I have with this mentality. Firstly, although I hate a nanny state as much as the next person, we must remember that every individual has basic obligations towards the society they inhabit in order to function within that society, or whatever. Proceeding from basic moral premises, perhaps I could say one of these obligations would be to not kill your fellow citizens, for such an act would be seen by many as immoral. However, the widespread possession of guns increases the chances of such an infringement.
Although a gun may, as you say, be used as a kitchen utensil, such a case would be an exception to the norm re gun ownership. The purpose of a gun is to kill or wound another living thing - therefore, most will buy a gun to fulfil that purpose. Imo, we must apply reasonable standards to the purpose of an object when determining who it should be available to - if you want a can-opener, buy a can-opener; not particularly onerous. Not everyone is a violent criminal, again as you say, but an abundance of guns leads to more instances of violence, nonetheless. Lethal action is an impossible (or difficult) recourse for someone without a gun, but no so when they do have one, meaning that, on the whole, people will be more likely to revert to use of force when able to in order to ensure the best possible outcome for themselves (eg, not being mugged etc.) in accordance with the theory that all people are ultimately self-interested.
The government banning things doesn't make them disappear.
Yes indeed, but this is a false dichotomy. Its not about whether they are present or not; it's a question of
quantity. If you make it harder to gain access to a gun, it logically follows that there are going to be less of them around. It may be possible to acquire a gun through the black market, but prices will be higher, availability lower than if they were fully legalised, if the police are doing their job properly. So, in my book, it is safer to legislate gun ownership and account for the possibility that a small fraction of the population may illegally acquire guns than it is to simply fully legalise gun ownership, meaning that a higher percentage of ill-meaning people are going to be able to gain access to them and use them to deprive the liberty of others.
Hopefully I've made myself clear.
