True, but it only takes a single country anywhere in the world to keep the internet free. And by keeping the net free, they'll get all the money, so they're is a strong incentive to do so.

1. Hidden services
2. Decentralized
3. Just create a pool mechanism where you contribute your private key for whatever gov Auth system exists, then use a random id from the pool among all sign-ups everytime you sign up for a service.
