So many companies are so nervous about having any user-generated liability that KYC is on steroids. Lots of services want to tie online accounts to physical identities (and, hopefully, those identities' bank accounts). Meta already pushed for drivers' licenses. Quite a few sites use Veriff or other services that match the biometrics of IDs with selfies/videos. Passport might be a bit too stringent but I can definitely see Musk wanting a document that conveys proof of citizenship which is a whole other mess, I hope all the non-US countries on the planet enjoy him having a cobbled database full of their citizens' identifying information.
