You’re referencing The Great Leap forward right? Because if so you’re completely ignoring the details in an attempt to use it to bolster your point. The reason tons of people died in The Great Leap Forward has nothing to do with food production per se. Rather, the Chinese government declared several animals to be pests and commanded everyone to eradicate them to protect the harvest. Among those animals were sparrows. Sparrows are minor agricultural pests, but they are fantastic at eating bugs. And so, having hunted sparrows nearly to extinction the Chinese were unpleasantly surprised when a huge plague of Locusts descended on their fields and ate nearly all of the harvest. So the real lesson is not that command economies are bad but rather that unforeseen circumstances should be avoided. If they hadn’t killed the sparrows we would not now be hearing about how many died.
