Some applications do require this level of identity proofing (scanning your passport in an airline mobile app to book an international flight comes to mind).

I don't know about presently but historically, you didn't need a passport to buy an international ticket. You needed a passport to get on the plane at the airport. So if you buy a ticket in a fake name, it's your problem if you can't fly and tickets aren't refundable for this.

Which is to say that no app space comes to mind when I think of something that needs id scanning - or the only apps like this are extensions of state control to the virtual space (virtual parole hearings or whatever).

Basically, anything that isn't the state should use it's own fricking account system to relate to people online. And the state itself is kind of iffy.
