I actually don't think violence should coincide with justice. It just does because violence is enforcement, and we don't have a better way laid out for peaceful coexistence (at least, not in the US at present). Violence exists, and one of the most reliable methods of regulating violence has unfortunately been to meet it where it is, with greater violence. Beyond that, we have a tendency to go to great lengths to justify violence against one another, so much so that it's an art in and of itself. I'm well aware how idealistic I'm being in wanting peace as a baseline, but nothing worth doing is without challenge.
Private property is a can of worms I can't touch right now. But I have ancestors that were considered private property, and existence itself is being claimed by the highest bidders with little that can be done to resist it. You won't find me arguing that private property isn't at the very least directly supported by violence. I'm not quite sure why I'd have to preach about it to substantiate my desire for peace though? I'm engaged in a system I didn't choose, and I find my rebellions where I can. It's hard to exist in these times without a bit of personal dissonance.
