All the things about "community" owned just raise the question that what are the structures the communities adopt, what are the roles and what are their rights and responsibilities, and how are people elected to the roles. And how do you make sure these communities don't end up like the existing communities (countries, companies, NGOs, etc...) that you are trying to differentiate from? You can't just have a bunch of people and call it community owned. By that definition then this world is already community owned, the internet is already community owned. You can't also just bypass humanity, this world is the way it is largely due to humanity, not capitalism, not socialism, not because it's not community owned. If the human beings in your community inherently have the same traits as human beings in other communities, how can you make sure you community doesn't end up like the other communities?
