There should be a protocol, in which voluntary individual participation is possible alongside identity brokers. This is one of those things that should have zero trust baked in at every level. It should require reversible data transactions, and real world mechanisms to allow legal authorities to reset or return ownership of ID information. It should work concurrently with a properly defined notion of valid, entirely offline identities to accommodate people who don't want their identity digitized. Multi signature cryptography and webs of trust are pretty mature concepts at this point. Using public notary systems could provide the real world authentication to publish keys, so the protocols could be developed around the idea that additional bureacracy and government shouldn't be needed - use the systems already in place wherever possible.
