> The highest friction version of this is that the credential ties to a real world identity somehow; maybe locked behind legal barriers, etc., but if a minor is caught using someone's credential, then the person whose credential they are using can be investigated, and, if necessary, charged with a crime roughly equivalent to providing alcohol to a minor. Without the possibility of real world enforcement, none of these identity solutions can possibly work.

Buying alcohol for a minor implies knowledge and intent.

Getting the tokens out of a phone doesn't require the user to do any of that, the user just has to be frugal and keep the phone longer than it's supported by the manufacturer, until some local exploit is found again, and that token will be extracted and available online for everyone to use.

Parents buy those phones, phones could easily have a "user is a minor" setting (and a flag sent to all the sites that want one) with a password for parents to unlock stuff if needed. This would be set during the phones first set up, and it's done. But nope, the plan is for everyone to install a form if a digital ID on their phones, and once it's there, requiring full-name identification when registering is just one step away.
