But in most people's workflows there is something special about the central server: it is the source of truth about the state of public branches. That is why losing the central server is so disruptive. It means you have to re-establish the source of truth somewhere else and get everyone to transition over to that new source. With a truly decentralized system the source of truth would be content addressable. For example, it could be obtained via a public key rather than a server's domain name.
