Same reason pretty much every new protocol fails. Nobody cares about protocols specifically. People care about discovering new and interesting things. If nobody builds anything new and interesting on a protocol then it's never going to take off. If the new and interesting thing that people build is too limited in it's interests (oh wow, you can use it to but drugs and commit crimes) then it's never going to really take off beyond a limited user base.
