I don't really disagree with anything you've said, other than a vague sort of discomfort around practicality. I dislike market failures very much, I war-crime dislike engineered market failures (the two co-occur with alarming frequency).

But markets are effectively part of the natural world: if you engineer the most oppressive, regimented, panopticon nightmare prison available to human deviousness you will succeed in creating a black market, not in eliminating markets.

So any solution has to be about preventing market failures, not eliminating markets. If North Korea can't effectively inhibit markets from forming, it's a pretty convincing demonstration that no acceptable amount of anti-market intervention is going to be okay.
