There's nothing stopping an 8 year old child from just taking their parent's ID to do Age Verification...

When I was 8, I remember being bored and curious and touching a lot of parents stuff... phones... wallets... legal documents...

Most parents don't put their stuff in safes...

Like... THE WALLET IS RIGHT THERE... I COULD JUST GRAB IT!

If they had age verification stuff back then... I could've just... quickly snap a pic of their ID and just YOLO it...
