We're playing with words here, but more like Garbage In - Garbage-Out I'd say. Too much information is available as input to decision aiding systems of still evolving (dubious?) design. These systems are then used to make potentially life changing decisions. With almost no quality control on this information and no control of the information by its subject (unless I'm missing something significant), it is a recipe for disaster.
In this context, I can't see the upside for Real ID, but neither do I identify it as the main culprit (military personel have unique identifiers, and I am not aware of any proof that they suffer from proportionately more information quality problems than do the rest of us).
I think we're putting the cart before the horse with this new law. It seems to me we should have first strengthened our information quality/information use/information liability and privacy laws, and then debated the merits of yet another identifier (we already have state ID, state DLs, passports, Social Security numbers, etc).
