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.
