Only in the Anti imagination does the ability to consent mean that the child MUST become the sex-slave of the first person they consent with. ( Meanwhile all the freedoms which undermine slavery MUST be disallowed them. )

Such as in Lolita.

This is why a society which recognized rights for child sex is simply unstable if it does not also recognize other rights in children. Naturally everything else would have to fall into place with consent. It is simply absurd to even pretend consent is being upheld, when a slavery status is maintained anyway on all or most remaining aspects, permanently undermining the capacity to consent and to refuze.
