Well, your premise is that people are too ignorant, at least sometimes. You don't blame them for being ignorant, instead you blame bad actors for creating the ignorance, but regardless liberal democracy still rests on the assumption that the populace is qualified enough to make important decisions.

You'll just buy cigars!" Citizen: "Well, yeah. That's the idea."
