There is definitely a risk of governments using this as an excuse to encroach upon civil liberties, as they've done in the past, but this is not a black or white issue. The reality is nuanced and passing regulation requires careful discussion and balancing. I'm sure we can agree that regulating Big Tobacco and Big Pharma was a good thing, and not some civil rights issue, so why is Big Tech different?
We can also work on educating people, as you suggest, but it can't be the only solution. Regulating greedy and predatory companies should be a part of it.
It's amusing that you would rather support a ban on screens in schools, than regulating companies that make using screens harmful in the first place. It's very reminiscent of the blanket "TVs are bad" argument from past decades.
