The centralization doesn't have to be broad styled like facebook. It can be communities based, which can and does also exist in real life. The issue with the real life versions are how they come to power, keep their power and what they do with the power.

In the steemit world, the total opposite exists. The only hegemon is the SP hegemon that consists mostly of whales. They have it and thus control the rewards to their desire. If you completely destroy the ability to allow hegemons to exist, then you also negate the ability to combat them. But that's not what we are talking about or see here.

What i'm advocating for stronger communities with people willing to put their SP to work, and the best way for that to happen is to have effective community leaders (and delegation).
