Buying alcohol online without having to show a website or a delivery driver my social security number is a challenge that needs solving. Same with picking up expensive parcels from package drop-off points in my country.

You can debate whether setting up such a system for things like social media is a necessity or desired in the first place, but being able to show someone a QR code that verifies my name and age without exposing all kinds of other details about me is extremely useful.
