My concern is very much those two concerns plus the fact that I value being able to be anonymous. We're increasingly losing that in the real world with CCTV and AI that would eventually allow people to be tracked (like in China), I do want to have one last bastion of privacy.
That said, I fully support laws that ban phones at school, I chose my kid's school because they do not allow any electronic devices on campus outside the computer lab where kids can go to to do research. Every day when I bring my kid to the school bus, I see that children say hello to each other and start chatting. There's another very well ranked school that picks up kids in front of my apartment and they allow phones. The kids all stare fixedly on their phones as soon as they sit on the bus. Having a country wide ban of mobile devices in all schools would I think serve most of the same purpose as the social media ban while having a lot less externalities.
