I completely agree with you, actually.

And I meant sort of what it sounds like you're talking about; some people under eighteen are mature enough to consent to various things others might not be. But, considering people aren't perfect, acting like everyone is is a recipe for abuse. That's all I meant; in a perfect society, with perfect people, you wouldn't need age of consent because everyone would just respect consent, and be able to read if someone is capable of giving it. But, considering that's not the case, that's why this is an absolute disaster of a scenario.
