I agree that a government issued identifier is a bad idea, but that debate is long over and SSNs won. The government can still stop corporations from using it by passing a law and enforcing it (and they have for some things), but that doesn't seem likely given the history and evolution of SSNs. It seems more likely that the government continues to require SSNs on more and more reporting, and continues to not punish other uses by corporations.
