Age of consent is bullshit.
If you can say you consent and can explain what consent means, you are capable of consent.
Any idea that there should be an arbitrary age limit because some kids might get "exploited" is bullshit.
Some old people get manipulated into giving away lots of their money, likely some kids will aswell, but that doesn't mean there should be any legal restrictions on "kids" because they haven't hit the right age yet.
Any reliable arbiter is going to be able to tell most genuine consent from someone who has been coached and coerced, and for the cases where it isn't, tough shit, thats freedom.
If we go down this road, then it leads to all sorts of bullshit ideas, like drug addicted prostitutes aren't capable of "consenting" to sex work because they don't have "any other choice", or poor Malaysian kids can't consent to making textiles because they're "forced" to do it because they "need" food.
