To steelman a response, in a way no socialist I've met would ever enunciate because they are usually not thinking that hard: capitalism works great in a framework where the use of force is restrained by some other entity. But the first thing you'll do if someone threatens your family is run to the strongest most connected person you know. Similar to how a bitcoiner might say frequent small crashes are preferable to generational large crashes, a socialist might say that infrequent democratically-sanctioned government aggression is preferable to generational aggressions by the next stronger warlord. History does suggest a certain level of scale of aggression is necessary to prevent complete annihilation and subjugation. Why not try to harness the demon if you can't kill it?
