> In most of the world, the ownership of "entities" is also public data. The privilege of being an entity is bestowed by the public through the state, and any status or license granted by the the collective (the state) is and ought to be public information.

Under that theory, bestowing the privilege of privacy doesn't seem any difference to bestowing the privilege of being an entity.

So why should we do one but not the other? What are the trade-offs?
