>there would be physical cities whose population consisted entirely of architects and engineers.
the analog to a digital federation in the physical world, is literally just that, an actual federation. People making choices about what community they participate in isn't technical, it's social. Everyone who lives in a democratic society does in fact participate in how their city is run and governed or understands how to move from one state to another.
You do not need to understand the technical details of federated systems, but it is absolutely infantilizing to pretend that people are unable to choose or build the communities they want, and take some responsibility in maintaining them. This 'consumer' mentality needs to die, people need to learn to be proper citizens on the internet. We ask it from people in the real world, so we can do it online. Why are we pretending the online version of some 19th century company town is inevitable?
