It takes a village to raise a kid.

You cannot parent in isolation and outside of society. How society is structured has an huge impact on parenting. It is delusional to think of parenting as some kind of thing that exists in isolation separate from and not influenced by the rest of society. Parents often can only have little influence themselves.

This is a value neutral description. Though I do think total parental autonomy in parenting is not a worthwhile goal and also not at all realistic. As parents you have to deal with society.

What does that mean for social media bans? To me mostly: network effects are wicked strong and fighting against them as an individual parent is basically impossible. This can lead to parents only having bad choices available to them (ban social media use and exclude them from their friends, allow social media use and fry their brains). Are bans that right solution? Don’t know. I’m really not sure. But I do know that it‘s not as simple as „parent better“.

In discussions similar to this I often see parents expressing their happiness with a state taking the role of a "bad cop" so that the parents can just wash their hands off telling their children it is state's fault they can no longer use TikTok ("I can’t express how much easier it is to restrict it and not seem like a kook when authorities are also on board." from OP) instead of having a proper conversation about harms of social media with the children. This is literally a cop out for them from a proper parenting.

From my point of view I'm already paying for their brats with higher taxes, now I will also have to gradually give my documents to random web sites more and more just to reduce the "burden" of parenting on lazy parents...
