My point: The failure of Communist regimes are not because the people who run them are socialists but because they are fundamentalists.
No, I'm pretty sure Communism being a shitty way to run anything larger than a farm has something to do with it.
How about many small farms for example?
Individually, yeah. Collectively, doubtful. Central planning would start to set in, and we know how disastrous that ends up being. Might work, might not. Probably dependent on the number of farms, and the personalities of the farmers.
