And if they want to do it, and not being forced by the parents, there is no problem that I see.

I'm being a bit of the devils advocate here, since I don't disagree with you at all. I'm just pointing out that not everyone agrees with other parents boundaries.

Children, are not property. At least, they should not be treated as such.

This is not in dispute. I'm keenly interested in understanding whether children have constitutional protection. I think they do.
