I largely agree with you.
But please can you tell me how you believe this differs from age-gating the purchase of cigarettes, lottery tickets, age restricted cinema tickets, alcohol, firearms and so many other things we already have age-gating on?
Edit: I’d love any one of the downvoters to comment and actually explain what I’ve said that’s so atrocious? We DO age gate many things in society and many, I dare say most, would not want cigarettes to be available to a 13 year old. So what is it about online that makes it so different? If we CAN make age checks online anonymous (and indeed the EU standard downright requires it) why don’t we want this online?
