There is research about when commons work and when they don't. SRSLY WRONG has a podcast episode about it
Edit: here is the episode. Basically we are more motivated to follow rules when we are included in the process of creating them. Then we also are willing to "police" others so no centralized force is necessary. Also it's quite a leap to think that the dominant system doesn't work because of a thought experiment. If it works in practice, it has to work in theory
