This pattern of thought is exactly the issue. Stop offloading the responsibility for creating a reasonable environment! That won't end well for neither children nor adults.

It's an extremely American religious belief that everything is an individual problem. Luckily, almost no other country has this religion.

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“.

This is not "offloading parenting of your child to the government" it is acknowledging that a certain action can be far easier to take (getting a child off social media) if the government puts in laws to support those actions. Social media relies on network effects, this might weaken those effects and make it easier for individual parents to keep kids off those tools. Not sure why it upsets you so much.

Are environmental laws are a way of off-loading all environmental care to the government?

Are laws against violence a way of off-loading physical protection to the government?

Yeah except the guy is a kook and an enemy to a free and open society.
