I am giving you perspective from someone that had social media limited. Not having a social media presence caused other kids to leave me out of things. I missed a lot of context on drama that happened online, and was always late in learning about things.
I don't have kids but I have been tutoring kids for the last 14 years, since I was basically a kid. I do individual tutoring for mostly high school, and occasionally middle school kids. Some of the have been with me from 7th through 12th grade, and a couple have even asked me to help them prep for finals even after starting college. They end up trusting me with things they wouldn't tell their parents, because I'm still someone they see as an authority figure. Because of cultural reasons, the kids I've tutor think of me and address me as an older brother. I've noticed covid catalyzed the shift to using digital platforms to keep in touch.
I don't have children, but empathize with the feeling of wanting to be protective. It took a lot of effort to make sure some of kids I tutored weren't taken advantage of by people like Andrew Tate. Telling them not to watch didn't help, pointing out the problems with Tate's message and taking time to dissect it did. Doing that also helped them learn how to identify similar manipulation tactics from other creators. It's important to separate the platform from the users.
I think we disagree on the importance of teaching kids how to use these tools. It feels sort similar to countries banning people from accessing AI tools like ChatGPT. The ban won't slow down AI development, those banned countries are simply left behind.
