I'm calling out the entire ecosystem. Consumer protection would have to be implemented in wallets, payment processors, marketplaces and most other services. I'm guessing it would look like something along the lines of the bip70 payment protocol.
Why does arbitration have to be built into a BIP? If people want it, as you and I have both said, any service provider can offer it with current functionality. So I think the discussion is at an end there because I dont think youll disagree with that statement.
I'll just say thought that everything else you say sounds like you want to implement control over bitcoin. Leave bitcoin as it is and let consumers choose what gets implemented through natural processes. BIP70 sounds like its intended simply to further identity tracking and it sounds like a horrible idea for bitcoin. Im sure some of your altcoins have that functionality built in. Bitcoin doesnt need it built in in any form.
People who talk about getting rid of governments don't generally sit and think up ways to govern things. You're talking about governing. If you really believed there was a market for it, then you would write some code and try to sell your service. That's my challenge to you. Go do it with bitcoin as it is today. Go make some money and support bitcoin in the way that you're so passionate about, which seems to be arbitration and identity tracking. Only, let consumers choose.
