> But it's a hilarious sign of worldwide government incompetence that social insurance or other citizen identification cards are not standard, free, and uniquely identifiable and usable for online ID purposes (presumably via some sort of verification service / PGP).

Singapore does this. Everybody who is resident in Singapore gets an identity card and a login for Singpass – an OpenID Connect identity provider that services can use to obtain information like address and visa status (with user permission). There’s a barcode on the physical cards that can be scanned by a mobile app in person to verify that it’s valid too.
