Adam Smith’s "invisible hand" was a feedback mechanism. Prices rose (signal: scarcity); producers increased supply (response); prices fell (correction). A market without price signals is a planned economy, and as the Soviet Union later proved, a planned economy is a network with deliberately broken feedback loops. Soviet factories reported output in tons—so they produced the heaviest, most useless goods possible. The system listened only to the Kremlin, not to reality.
