and they never will , govt has far too much at stake by controlling ID system than giving it away
They already gave it away and unless they're a couple of decades ahead of where they appear to be they'll do the same with digital IDs. Numbers for passports, driving licences, social security, etc. are all unique IDs that can be used by anyone, wrap them up in a decent layer of security and anyone can prove they have a government issued ID without giving away any details on what it actually is, just that it matches.
I really don't understand why you're so determined it must be photos, it's pretty clear it's just about the worst option but you're dismissing all other options with little or no grounds.
