LOL, erroneous reasoning. There is 1 database called Steemit, and it is centralized information, yet not centralized power to control that information.

Ahhh you're talking about Steemit... ok, now I understand what you mean with "centralized information". I was thinking about 1 big source of information, not 1 big channel with lots of sources.

Efficiency doesn't trump what is more right as respecting individual rights of people. The efficiency excuse is what have been used by authoritarians for ages.

Sure. It's an excuse but it's also true. That's why business have a CEO. That's why Steem have a delegated proof of stake (right?).
