Then what would you do about ISPs that trivially innumerate the entire public relay list from a directory authority, and block every last one of them? What happens if a government (such as the United States) demands the private keys for the Directory Authorities? Would you even know if it has already happened years ago? A unified concensus on the relay list (for the public relays in relatively free countries) is fine and all, but what about the less free counties? What if many countries together begin null-routing Tor relays in their BGP routers? You would do nothing?
