While the pirate in me says "hell yeah!", the system administrator in me says "Fuuuuuuuck". I was once part of an IRC network, and one of the biggest issue we had was with Brazilians who would break our rules and get banned. Just a minute or two later, they were back. It got so bad that we just said "Fuck it. We're banning all of Brazil." Not an ideal solution, but it beats spending our time chasing the majority offenders. It's the 80/20 rule, where 80% of your problems are caused by 20% of your users.
Now let's pretend somebody builds their new app around this new tech. I love the concept, but how do you keep order? How do you ensure people follow the rules? The only thing keeping users in line would be the fear of losing their "brand" (their username, their reputation). If the new app is something like a chatroom, there's no "brand" to be had, and you can simply use a new name. It would, obviosly be very different if the app were based around file hosting like Google Drive, because you don't want to lose your files, but anything with low retention will likely be rife with misconduct due to anonymity.
On the other hand, it would allow for a completely open internet, that no single government can shut down, which we're seeing happening more and more, with China, Iran, Russia, and Myanmar all shutting down the Internet, or portions of it, when those in power feel there's a threat to the status quo.
It makes perfect sense. It's about control by any means. The fact of the matter is that, by definition, conservatives don't want progress. They'll say and do anything to stand in the way of progress, even if it's contradictory.
