Agreed. You aren't going to get this to work with Wikipedia. But I could see some utility on the small scale (if it weren't easy to break with conflicts). A Discourse install for local discussion in an oppressive regime run across a few hundred commodity computers could be pretty hard to shut down and reasonable to have work for 50k people, the weakness here is that one bad actor could disrupt it just by flooding it with valid but conflicting writes (not to mention being able to just issue deletes against all the state if all actors are treated equally)

And don't expect it to support normal transactions or participate in distributed ones
