You could of course key on things like SSNs, but data brokers wouldn't be very happy about that because there are lots of SSNs tied to multiple different people.

		The government will, given that they're a fairly integral part of how the US economy. Every single financial institution relies on these data-brokers. U-haul needs data brokers to be able to verify your driver's license, the TSA needs data brokers to let you on a flight without an ID. There are simply countless of reasons for why you wouldn't want to break this system for people who haven't opted in for breakage.
