i mean, there's this kind of cultural misunderstanding of contract law, as borne out in decades worth of hollywood film.
"did you read the fine print?"
but, it's a nineteenth century concept of law, it's not reality, and it hasn't been since before the emancipation proclamation. there's all kinds of rules about what can and can't be inside legal contracts, and judges rip them up all of the time.
you can't sell yourself into slavery.
and, you can't consent to much, as a child.
