The culture of having them everywhere seems insane and its negative social consequences seem manifestly obvious.

I am sympathetic to the stuff around the capacity for violence not being monopolized by the state, though pursuing that seems fraught at best. If anything I see a stronger case for anti-tank weapons being available but blocking shit like handguns that seem dogshit in war but great for roadrage and murder-suicides; unfortunately the ideal case of a gun that only works on fascists isn't available.
