I haven't read the details of the proposal, but I'll compare it to my ideal situation. I'm in the US so my view is influenced that way. I loathe that my Social Security number and/or signature is the key to my identity. I think every individual should be able to choose how they are "identified". If you choose to be identified by the government system, fine. If you choose to be identified by Equifax, fine. If I choose to be identified by a gpg private/public key pair, I should also have that right.
