I’m not against this being a method people can employ for verification. But it won’t be the only method. I’m not going to ask a recovering alcoholic or a Muslim to walk into a pub and buy a beer.

Also: it’s users under 16. Not under 18. While I’m not aware of any users under 18, we did have a 17 year old last year.

This method has been considered, but it wouldn’t catch everyone.
