Can age assurance be done privately and anonymously? Absolutely.
But the entire point of age laws is to stifle free speech and ruin privacy. Thus why every age law requires uploading an ID.
If it was just age, just require a credit charge of a $1 through an intermediary. Good for a year or whatever.

Does it? I mean sure, it's a side-effect that some (most?) politicians might find desirable, but there's also people who just want to restrict access to adult material (not taking a position on whether it's a good or bad thing here). Most parents would probably agree with the latter even if they don't with the former.

The age verification system currently undergoing large scale field trials in the EU does not require uploading ID. Every member of the EU is required to support that system, and any online age verification laws any member passes are required to allow its use.
