Hmm... This sounds a little bit too complex. I'd like to keep things as simple as possible.

I'm also skeptical if political philosophy is a good way to think about this. Blockchain governance and subjective proof of work might require totally new systems. Which one works well can be found out only by trying several different systems. Some of them will work and some of them won't – for reasons which are hard to see before system is actually in use.

We have to remember that there will be many subgroups in Steem in the future. There will be different languages and a lot of people who don't speak English. Some subgroups never communicate with each other and have no idea what others are doing. How does the voting system work in that situation?

Btw, if somebody is interested in democracy, Bryan Caplan's book The Myth of the Rational Voter: Why Democracies Choose Bad Policies is a must-read.
