I don't think this will ever work on bitcoin. This proposal is only applicable to a government or a small group of people wanting to have some leader-figure in their community. Bitcoin has been okay without any central figure of authority for the past 9 years, and lots of genuine and clever ideas have sprouted due to the decentralized nature of the network. If we were to have someone as a liaison, wouldn't that give this central figure some sort of hunger for power over time? We've already witnessed how grim it could be with our present governments, and have we learned not a single lesson from that?
