Peoples obedience to authority didn't change much in general, it's an instinct for survival, it makes the surrounding society and feedback from a society more predictable.
Online bubbles are often subcultures that predate the web, what changed is that many of them became more attractive or commercially viable through independence of location, new viable markets linked to a return of investment, which of course motivates virtual landgrabs and people defending their territory.
It's not a suprise that most online communities have their own authors and authorities, stores, books and conferences, their own terminology or language, their own culture/church basically. It's even obvious within niches like programming. Coming up in such a community is linked to wealth. If you're seen in church and competitors not, churchgoers will likely buy from you.
Abolishing cultural independence would lead to a China 2.0, cultural authority in hands of the state. Likely less innovation caused by a lack of cultural diversity, less motivation to invest into land that's already been grabbed by others.
How can the problems that are likely caused by cultural independence be solved without fully centralizing cultural authority? Can something like a driver license for the web even be possible or be fair?
