In the US we each have a Social Security Number, which is a central government ID. I think that would be sufficient for user assignment SSN alone shouldnt be sufficient for account creation so you'd probably have to jump through the usual 2-3 forms of ID to get access to your account, but then the email itself could act as another form of ID. Which would be super useful in lots of situations, especially if you lose one of your other forms. Also there is a lot of digital user verification workaround right now that would be solved by this. I would much rather interact with a government controlled email address than scan and send a copy of my drivers license to online services
