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.
