Needing a gun to defend oneself against someone who also has a gun is a circular argument. Laws can and are changed - unless the legislators are hostages to irrational forces, such as religion and/or similar persuasions (holy 2nd amendment). Take the guns away across the board and you arrive at the European situation - there is no suggestion anywhere in Europe that members of the public need guns to survive, whatever their remoteness.
It would make sense to say everyone needs to have a fire extinguisher, big (even huge) ones if living far away from a fire service, but guns.....
What I was saying is that this is a uniquely USA problem and it is their problem for them to solve, but they tie their own hands behind their backs, a bit like governments which rely on the support of the clergy and/or evoke deities in their rhetoric in building up their legitimacy.
