The closer you get to implementing this fantasy Communism, the closer you get to death. That's why nobody can do it, it's why nobody ever has, it's why nobody ever will. It requires a staggering amount of aggression and violence to even attempt Communism, much less these idealized versions (which require 24/7 perfect violence to be applied to disallow even the slightest step outside the framework by the population).
What we need are anti-trust protections that prevent the formation of `too-big-to-fail` entities of all stripes.
It was that way, agreed but might not always be that way.
Because free market economies have their own share of inefficiencies and moral hazards and certainly cannot be the efficiency pinnacle of human civilization.
I don't know what computers and networks will be capable of in the future, but it's worth noting that command economies failed in the time before these things really took off. The weak link has always been people who's brains developed in a time when they were monkeys scrabbling under trees and screeching at their fellows. No wonder they can't efficiently run big systems. But it's becoming evident maybe these tiny self centered brains are just big enough to design something that _can_ run a complex system efficiently.
