This liability insurance requirement would have to go all the way down the supply chain as well. I'd imagine this could work in the context of either a state or anarchy. Thoughts?
Well, "insurance requirement" wouldn't work too well in an anarchy, but requiring restitution and
allowing insurance to pay it would, and have effectively the same result.
That's a very AnCap method of doing it.
How would AnCap deter jihadists from acquiring nukes? Or anyone else who would value the nuke more than their own lives?
"AnCap" doesn't, any more than "laws" do. Even today, it's down to individual responsibility. I'd think that manufacturers, held personally responsible for who they sell to, would be pretty discerning, yes?
Restitution is capped at one's lifetime income.
Indeed it is... but something is better than nothing.
