I mean, it has worked historically, just extremely rarely. Singapore was one such recent example.
The issue is that people die and the next person usually fucks everything up again.
Anarchy has similar issues.
The real problem is just us; humans.
That’s the next core idea: power structures attract the wrong people. Take Stalin who was worse than Lenin. Lenin had benevolent ideas but got corrupted, Stalin took that position with bad intentions from the start.
Fatalism only serves the status quo.
It’s not fatalism, but fact. Humans are the real issue. We weren’t biologically evolved to deal with such large groups, along with certain other DNA quirks.
That said, with technology and/or time such a flaw could be fixed so that we either are able to overcome our biological shortcomings, and/or technology allows us to achieve structure without hierarchy while also preventing hierarchy from springing up as well.
I don’t even know where to start. At least understand that this is beyond the realm of facts. And there is a reason, anarchists try to keep things on low levels, in small groups, as far as possible and build “communities of communities” bottom up. I don’t understand how technology is supposed to help there but there are structures that prevent hierarchies already.
