So, if it were made legal for adults to have sex with children, tweens, and teens, then I'm afraid we would have another problem for those same children, tweens and teens. That of harassment. And I'm not talking about the "MeToo" type of harassment although that could be included.
I mean the common, everyday street harassment that every woman knows all too well. Anything like pinching, butt patting, called 'sweetheart' by strangers, cat-calls, ordered to "smile!" and so on and so forth. And this would also include pedophiles hanging around places where children congregate to try and engage them.
I bet they would be three-deep outside of schools!
It would make being a child/tween/teen almost intolerable.
