Hey, V! Welcome to our forum!
Moderators: I can confirm that his story about the most recent time we saw each other checks out. (Also that this post is totally his style.)
Vitalik, you can vote in Community sentiment collection: Poll on NU4 dev fund ZIPs!, and I hope you do — just to increase the signal available to the community — even though only the votes of people who had an account more than six months ago are going to be counted by the Foundation (as an effective Sybil-resistance technique).
As to your post, I agree with Tromer that it is excellent, and I agree with you that there are promising ideas under development for identity systems that are “open” in some sense and censorship-resistant, but I also think that identity is overrated. We can do a lot of things just using public keys/addresses and local names—in which case we don’t need global names—and we can avoid a lot of the collective action problems that your post is about by minimizing the need for collective action.
Not that I think you yourself are mistakenly overrating the need for collective action, and therefore the need for identity, but I think most people are.
Anyway, there is a collective decision process going on here and now which, despite the daunting theoretical impossibilities is going very well. So go vote (in a non-binding signaling-only vote since you are too new to the forum to be automatically identified as a probable non-Sybil) if you want.
Oh, also you can vote in the coin-holders poll, which is also theoretically impossible to secure, but which I also expect is going to work fine in practice.
