For a more fair comparison to liquor stores and adult movie theaters: it would be requiring people to be 18 to sign up for internet service, which is how it already works.

Parents are buying the alcohol from the liquor store (internet service, which kids cannot buy themselves) and giving it to their kids.

If you don't approve of the alcohol you're giving to your kids then stop giving it to them (it is legal in my state for parents to buy alcohol for their kids). So what if other kids are drinking too and it would be socially a pain for the kid? That's always been true of having a parent with stricter rules.

When I was a kid in the 90s my parents limited how much TV we could watch. I knew other kids who could only use the family computer for a limited time and while their parents were in the room.

I sympathize with parents who do want to provide internet service to their kids and want better parental control software.

But making the internet worse for everyone is not the way. Discord has already had a partner leak IDs before. [1]
