Do you have a solid set of examples of wide spread gun ownership (by people without military training) in various geopolitical scenarios, especially those with limited government, or as in the scenario favored by myrkul, no government?

You might want to think through various scenarios, such as a high density apartment building, with plenty of children, where most renters, without military training, choose to own a gun because they feel compelled to own a gun due to the society they live in.
