> centralization and hierarchies are far more efficient

Efficient at what? Dictatorships are efficient at maximizing centralization power (and therefore creating wars), not efficient at making citizens happy.

Private companies are efficient at maximizing profit for the shareholders, not efficient at making employees and customers happy.

> With democracy, you spread the decision making across a vast number of under-informed people, which seldom results in superior outcomes.

Wrong. You are trying to applying direct democracy at specific, technical decisions. This would be like passengers on a flight voting on what flap configuration to use.

But democracy is not the Borg and does not automatic mean "everybody decides everything together". Specific knowledge and division of labor can still exists.
