they did it for years in a significant territory. the state had no power there during that time. that was a success, even if it was rolled back by a nationalist military (supported by nazi Germany) and undermined by authoritarian communists. also, again, there's rojava & zapatista Mexico currently, plus other historical examples. why are you demanding an impossible standard of perfection before you are willing to fight for a better life for yourself and everyone else? that's just doomerism and it serves the capitalists.
