>It's barely a step up from the "I'm over 18" buttons on websites.

i think its a pretty decent step up from that, but i know what you mean.

>I don't think the politicians will be satisfied.

and that circles back to my original point. the politicians aren't satisfied with a "mostly effective" solution (e.g. OS-enforced age attestation) as they are with literally every other law, and instead are taking advantage of the issue to justify mass surveillance.
