Because children are under the control of their parents and can't consent to thousands/millions of adults watching them.

This is no different than regulations around child actors, which are widely considered good and necessary protections of vulnerable children.

Yes, but their parents can consent for them. This argument is weirdly circular.

> Yes, but their parents can consent for them.

The point is that there are some things so risky for kids that parents shouldn't be able to "consent for them". One of those things is child labor.

Circular doesn't mean what you seem to think it means.

Parents have control over their children, but society has put boundaries on what they can do to them because parents are capable of great harm. There's nothing circular about that.
