Oddbean new post about login | logout Real communism has never been tried?
An anarchist form of communism was indeed tried in Spain to varying success. They were eventually overpowered by fascists and centralized communism. https://theanarchistlibrary.org/library/murray-bookchin-to-remember-spain-the-anarchist-and-syndicalist-revolution-of-1936
How to you make people share everything in a voluntary society? Who enforces that?
Emphasis on voluntary. If you don't want to be part of the production process, you can advocate for change and get consensus on that, or setup up your own society where it works the way you want. That's a lot how bitcoin works, doesn't it? Don't like the way the protocol works, submit a BIP and convince others its a good idea or fork the software and build your own network.
