Flip it round: if you have $999,999,999 then would it not be rational to expect random violence against oneself? I’m not saying it’s justifiable, just that it is prudent to expect to be targeted by crazies.

Flip it again: as a crazy, isn’t it reasonable to enact violence against Johnny Nine Nines? If he’s so innocent, how come his house is behind two security fences?

To be a little more reductive: my house is made of gold bricks so I hired an extra-legal anti-marauder militia, but now the marauders see me as a fair fight because I chose extra-legal militia instead of cops and judges… game on and QED.
