We're in the process of figuring out composite keys don't work :) And yes, State + State ID is a decent substitute for a national ID. Because it is a national ID. Except that some states will implement it in the shittiest way possible, and so we end up with even more of a lowest common denominator than if the states negotiated a standard. And one could reasonably make the case that in this day and age, IDs fall under the Commerce Clause. Here's the ugly truth: People are objecting to a national ID because it's an easy-to-parrot talking point. The rational objections are on thin ground. (Basically, the downsides are already existing anyways, we're just not getting the upsides. Because ideological purity. Yes, I mean you, ACLU)
