You're missing the collective action problem. When 95% of kids have TikTok, telling your kid "no" doesn't just mean having a conversation about social media harms, it means making them a social outcast. Sure, you can be that parent, but you're choosing between your kid's mental health from algorithmic content versus their mental health from social isolation. Individual parents can't solve network effect problems, that's exactly what policy is for. This isn't laziness, it's recognizing that some problems require coordination beyond the family level.
>I often see parents expressing their happiness with a state taking the role of a "bad cop"
As an actual parent, I have never heard of this or seen it. Can you provide some real examples?
> Can you provide some real examples?
How is the quote from OP's comment that is right at the end of the sentence you cited not a "real example"?
You said you've seen it happen "often" and provided no examples other than the one you are using to make your point. You implied that you have heard it multiple times in different contexts. I was asking for some of those contexts because as someone who is a parent and interacts with other parents frequently, it is not something I've encountered.
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...
