In the first paragraph you say that the parents should keep kids from social media.

Not necessarily. It’s up to the parents to know what their kids can handle.

Keeping kids off social media doesn’t have to be a privacy violation. If you don’t trust your kids to follow the rules, don’t give them access to devices they could use to violate them. If I give my kids access to a device, it’s because I trust them with that device. I don’t put any parental controls on it, either I trust them or they don’t get the device. It’s none of my business what they do with devices I trust them to have.

Kids need discipline and trust, not policing. If they break the rules, discipline them (take devices away and whatnot), but don’t surveil them.

And yeah, the laws don’t matter as written because good parents will help their kids circumvent bad laws. My problem is with the government thinking it has a say in how I raise my children. The government should only step in if there’s abuse, but other than that, they should stick to advising parents by providing high quality research to parents.
