One of the core ideas of Mao in the mid-20th century was to divide China into completely self-sufficient entities of about 3 mln. people, who should produce EVERYTHING without any trade whatsoever - because trade breeds wealth, which breeds inequality. They were supposed to mine their own iron and smelt their own steel from their own territory, for example.
I find I cannot pidginhole this statement in an easy anti-communism idiom. While it may be addressing the failures of communism (read centralized planning), it actually holds rather well on a long view historical suggestion. Mao was talking about peasant-farmer communities, and ones of around three million people, with strategically divided borders, could easily continue their existence at a turn of the century (for North America) standard of living.
Just saying, there's nothing structurally wrong with the idea.
Unsurprisingly, didn't work too well.
