When carrying a concealed weapon for self-defense is understood not as a failure of civil society, to be mourned, but as an act of citizenship, to be vaunted, there is little civilian life left.
It's an interesting way of looking at it that we haven't really considered. Every home a castle, every person a lord, everyone armed - for protection. People have a right to safety, after all; we gotta be able to keep the threats at bay.
What about when guns run out of bullets, though? For security, you should be able to have a back-up weapon on hand. Swords work well. That, plus expand your territory to keep the bad guys out. Maybe hire a few security guards to keep the peace. Oh, and export potential bad guys. If they put up a fight, you just have to make sure you've got the better weapon.
It's like history, only in reverse.
No wonder Game of Thrones is so popular these days.
