He probably thinks wow why is it that nobody ever considers that this problem would go away if we just came up with a better system for identity, such as how PGP works.
I like the idea better of making additional keypairs that have a chain of signatures back to your social security card so that you don't have to rely on it as much. It seems to me there's a lot of things that could be very workable as far as this is concern, but just to be clear I just like to use PGP as an analogy to a system that could work.
(This is the same logic many use for opposing backdooring encryption, since often it boils down to key escrow)
