But while I agree that tech alone wouldn't fix much, using a single number (with no biometrics whatsoever) for identification is just asking for trouble. Even my bus pass has my picture on it!
The real problem in the US is that for any newly proposed identity system, any protections that keep the private sector from hooking into it for their own commercial surveillance will get scrapped due to lobbying. At the present, even social security and license plates are just basic government mandates, but form a foundation for unrestrained commercial actors to implement totalitarian surveillance.
So given that, the sensible freedom-preserving USian position is to be against any new identity systems until some laws have actually been passed to prohibit abuses of the current ones.
The real legislation that is needed is to statutorily shore up the banks' liability for the damage their negligence causes. A person that has to deal with fall out from a bank being defrauded (eg repudiating that bank's and surveillance bureaus' libel) should receive a decent hourly wage in liquidated damages.
