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.
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.
