The problem is the US would first need to grow the political will to ban most businesses from demanding and then long term storing that ID. As it stands right now, for needlessly invasive things like supermarket discount cards you can just give them a bunch of fake info, and get a new nym every year or so to make your history less useful. But with an unrestricted smartcard ID, there would be no escape from the commercial surveillance web. Something like the GDPR is a hard requirement before stronger identification is palatable in the US.
