This is what representative democracy with an executive function is for. The government / executive acts without the need of democratic micromanagement, but is subject to popular oversight through a number of mechanisms.

Even in the case of democracy, you have to put trust in the sovereign.

And whenever the sovereign enforces a law, the person facing the enforcement will consider it tyranny. It’s a known paradox of the power we, the people, grant to the sovereign.

A thousand times no. A true democracy earns trust through the integrity of its institutions: executive, legislative and judicial, and the respectfully balanced and constitutionally limited powers they share.

Never in a sovereign.

democracies are highly centralized.

delegation is not the same thing as decentralization.

democracies and authoritarianism are both centralized, the difference is that one is a cooperative model, the other one is not.

My point wasn't to draw a direct line between democracy and a decentralized network. I just thought it was important to point out the risks and potentially short sidedness of giving up on decentralization because its slower and more difficult. That line of thought leads to more authoritarian control, and that's never worked out well for the average person in the long run.

I don't recall that argument in practice. In Kazakhstan just now for the leader has recently used the argument "Those who don't surrender will be eliminated" which seem more common than "centralization is easier and often cheaper" as far as I can tell in such situations.

I was speaking generally not to any one authoritarian. I can't imagine many, if any, authoritarian leaders would be using the "it's easier and cheaper" argument when grabbing more power, but its a very common argument used in more general and philosophical debates.

Look into any of the writings that led to the USSR and you'll find it all over. The goal was total government control would be the best way to optimize resource allocation. They were making the case that Soviet communism would win out against fascism because they could make everything faster and cheaper.

I might be crazy, but reading this I imagine a blockchain based temporary democracy: full proof-of-whatever correct voting scheme choosing a temporary centralized “government” with measurable goals to move the system to eventual decentralization.

This is actually one of the few uses I know of that I have a lot of hope for. I worked on a digital voting system in college a decade ago, we were researching accessibility concerns mainly related to visually impaired voters. The voting industry in the US is just as much of a tire fire now as it was then but it could easily be improved.

A blockchain based voting system with each state acting as a PoW validator could actually work. The main challenge is how to centralize key distribution in a way that is accessible to everyone without compromising anonymity. If anyone knows your public key they know exactly who you voted for in every election.
