What a loss that the Chilean experiment was never fully realized.
Command economies don't scale. Their inefficiencies are perhaps acceptable in groups of humans from the size of a family unit to perhaps a medium-sized corporation, but when you're talking about an entire polity, the deadweight loss just becomes too great.
And I doubt you'll ever be able to escape the problem that allocations, heck, everything in a command economy ( https://en.wikipedia.org/wiki/Soviet_Census_(1937) ), is political. Since you're replacing an amorphous blob of zillions of individual actions with those of a few.
Interesting.
