In general, I agree with you, and for the record, I'm in favor of general restrictions or limitations on social media for children. At the same, I want to add that I was not allowed to watch violent cartoons or play violent video games as a kid in the 90s. I felt left out on the playground when I didn't know how to play X-Men or Power Rangers or whatever. But in retrospect it was fine. I'm not sure the social isolation factor in particular is as dire as you claim.
