Wormhole requirement: "the URL of a publicly-available Rendezvous Server"
This means its not a self-sovereign system, like Bittorrent, GIT, and Bitcoin. Its no different then a central Napster server, the one that got dragged into court on November 1999. Scientists are still working on creating self-sovereign peer-to-peer systems. Its hard, but we're going to solve it in coming years.
