I'm a little conflicted on this. I think I understand what you're saying about an "imaginary hierarchy," in that our worth or status should not be tied to the size of our account. I agree with that.
Still, the term does carry some meaning outside of social status. It is a descriptive reality that the more SP you have the more bandwidth you have and the greater impact your votes have. I am willing to argue that these positions can influence the moral and social responsibility that you have, given the way that it effects how the system runs.
That's really the biggest problem with decentralization, it becomes this pseudo pure capitalistic thing where the ones who have the most resources has the most power
Absolutely. Decentralization is a form of privatization, which is a capitalist's dream scenario. I think open markets can be magnificent things. But I also know greed will always try to exploit the unregulated nature of those. A great decentralized platform needs to think about how those forces ought to be addressed and have parameters to keep them at a tolerable and functional level.
