People spontaneously form self-organized communities based on collectivizing reproduction during periods of prolonged insurgency. I call these communes, and consider them early forms of social reproduction that could come to dominate under communism. When large numbers of people directly confront the state and capital in forms that bring them into a shared location for multiple days, they often develop practices for collectively procuring food, cooking, and shared eating; for sleeping arrangements in proximity to each other; for sharing child rearing responsibilities and aiding disabled comrades. All work to share the work of care, to enable diverse participation, and to protect each other against harm.
