Amen! The only point I would add to your argumentation is the relative stability that we all need to collaborate. Imagine that you interact with a given community as one institution, and then a few months or years later, this community doesn’t exist anymore: then how do you honor your agreement? That’s why I think it’s crucial to balance this local hyper-liquid model of communities with a global governance level, that is as long-standing as the Earth itself (until aliens pay us a visit or we become an interplanetary species) and can keep track of all the changes as well as arbitrate on issues that concern us all and require some consistency in time and space (human rights, scientific research, environment, etc.).
