I don’t think this is as hard of a problem as people make it out to be. Why not just take fingerprints, plain old ink on paper, in lieu of ID? Or a photograph of your face that is immediately printed and signed, they already do this at airports. You should have to leave some form of identification but there are lots of free, easy and instant ways to do this that don’t exclude anyone.
