Short, glib comments get dunked on here, but you've got a point. As the saying goes, “The best argument against Democracy is a five-minute conversation with the average voter.” The judgement of the common folk is not unassailable, and is frequently wrong, which is why Democracy needs numerous checks and balances.
Democracy is a hedge against worse outcomes, not a guarantor of future outcomes. You might get your heart’s desires in the service of a King, but he’ll still be King and you’ll now be his subject.
