While I like your message here, I don't think authoritarianism is actually more efficient (efficient at what?) usually. Because often it goes hand in hand with economic and social extraction, which is inherently inefficient.

But I take and am a bit heartened by your main point - while the best case authoritarian regime can plan and execute more quickly and with greater efficiency than representative government, the worst case authoritarian govt is much much worse than the worst case possible with a functional democracy.

They are not more effective. They basically always end up as highly currupt ineffective mess.
