If we need regulation of "this harm", then what we need to be regulating is the social media networks, not the children (and adults!) that use them.
We need to be banning algorithmic feeds. We need to be banning promotion of hateful content. We need to be banning moderation that is biased against marginalized groups, or against criticism of the platform.
If they weren't being subjected to feeds specifically designed to create maximum "engagement" with fear, hate, and self-doubt, most young people using social media would be interacting in similar ways to how they interact offline. Perhaps there would be a little less inhibition due to the feeling of anonymity, but overall, anything harmful they might be doing or saying to each other on there is very similar to what they would be doing or saying to each other in person, regardless of what social media you let them access.
