I heard you can't even fly domestic in USA without a digital id. They tried to roll out digital id in Australia during Covid and nobody signed up. most people were just writing down fake names and fake phone numbers on the paper form whenever they had to do a sign in. A lot of people think it's the reason behind the social media ban for under 16s, force adults to do age verification. And digital ID is going to be the "convenient" way to verify age.
