I like the idea of anarchism, but I see it as more of an ideal world view than an actual stable reality.
To support this, every group member of every group must almost unanimously support the concept. When resources or safety in an area become scarce, it’s easy for some groups to evolve back into another power structure to take care of their own people.
It’s really difficult for me to imagine everybody on this planet getting along with this. But I’m certainly interested in other viewpoints.
Well, in many other systems you have an overarching ruling layer that sets laws and is able to enforce them from a top level.
That is precisely the reason why those systems can be relatively stable. As you just have a very large group of people following the same set of rules.
