What humans come from nature with doesn’t scale to the world and numbers we have built for ourselves (ie past Dunbar number). You can also train a neural net with pen and paper but can’t really build a product that can function in the real world.
All those structures are attempts at trying to test and train a particular architecture of collective intelligence that can scale to real world problems. Obviously all have failure modes and difficulties in innovating and transitioning, but they also have working proof of some degree of functioning. And the hierarchies they form are not caricatures of a tree data-structure, they are much more complicated topologies, because they are more emergent phenomena than conspiratorial captures.
Chomsky’s anarchism seem to define an end state without any prescription on transitioning or path dependencies in between. It also doesn’t have any demonstration on success with negative edge cases. If anything all utopias so far have devolved into dystopias, hence the hesitation.
Even with the most pleasant things in life we are prone to construal level fallacies. Going to Paris sounds awesome right now but my current excitement doesn’t match the moment to moment reality I will face; every minute of the long haul flight, the jetlag, sore feet from walking etc, I don’t even consider these. Our design documents never match our implementations. That is why I am wary of claims like “I can rewrite this system from scratch”.
