Wow what a great post, and many valuable thoughts! Interesting that you see the bps not in the executive branch, where i'd had put them, since b1 will drop out from this after June 1st. Absolutely agree, that we need some democratic element, here, but currently this is difficult as long as you'd need to handle sybill attack. It might be possible by limiting votings to a certain degree of reputation.
Also find your stance on arbitration interesting, asking for democratic votings of Arbitatrators, haven't thought of it as, its structured in chambers, and i feel it's a similar setup in eos. Still as dapps can choose their arbitration forum, this might be a sense of voting as well, but certainly has it's own pitfalls.
