I agree. It’s a problem we already have.
Drivers licenses are the de facto one today. You can also get an id card for those who can’t drive.
But it’s fully incumbent on you to do it. You have to arrange transportation to get it, have the free time, necessary documents, live close enough, etc.
That already causes problems for people, and is getting worse as voter ID laws get passed.
“Everyone gets an ID once you’ve figured out these riddles three and gone on a quest” is a stupid system.
