Anarchism is prone to polarisation dividing communities into smaller groups. You could not have a large society with anarchism. It only works in small communities, and turns tribal.
The various forks and splits in crypto communities confirmed that old idea.
Good analogy. Although I would view the ability to fork real communities as a feature rather than a bug. Resolve conflict by *not* resolving it. Just fork away peacefully.
We need to come together as a species. Having reap communities fork would likely lead to extinction. We need more globalisation for real progress, and to secure our future existence.
