At its core it seems like identity services are something that the government should be the source of truth for. They're already being used for that in one way or another whether it's checking a driver's license or SSN, but those are misused in terrible terrible ways by private companies. I should not be in a position of having to treat what was originally a mundane identification number as some extremely privileged permanent and unchanging password. It would not be technically onerous for the federal government to establish a secure federal identification standard. Giving every US citizen and residents an identification card much like what's already widespread within the DoD for CAC cards (Yes I'm aware the last "C" stands for card). Ditch SSN cards, driver's licenses, and other generic state ID cards and unify with one purpose built identity system instead of a hodge-podge of separate ones between the states and federal government. Ban the use of SSNs for anything after an effective date and require proof that some contract predates this deadline to have anything even tangentially related to SSN admitted in court.
I just wish someone would drag both political parties kicking and screaming into the modern age. Give Republicans their voter ID requirements they claim to want so much and give Democrats mandatory widespread adoption for every citizen homeless or otherwise. Make it mandatory to even pay income tax.
