Yes, we get special thugs that protect what's of each person.
Sure, it's probably even more violent than a literal mob trying to steal my stuff just because they want to. Well, it was that way in the Neolithic (raiding settlements) and that's why its inhabitants decided to have some kind of protection by and for the settlement.
It's literally not that hard to understand: you use force to prevent people from raiding your settlement, then the settlement grows with more safety and that's literally how we stopped being either nomadic raiders or afraid and impoverished farmers.
