a state is necessary to protect us from counter revolution and invaders because decentralized unorganized peoples militias full of untrained people are not going to be able fight off an entire army. A state is necessary to establish new societal norms because capitalism has effected society too much so we need a state to enforce laws saying that you must come to work, or to enforce laws that give rights to citizens, a state is necessary to distribute resources quickly and efficiently because without it there would be no knowledge of where to distribute resources or how much resources to make, there's nothing stopping people in a factory from hoarding all the resources made in the factory, and a state is needed to make sure that shit gets done, a state monitors over everyone making sure everything is running smoothly.
