Unfortunately I think the net effect of this overreach is that any such discussion will be overwhelmed by noise.
The Netherlands banned phones in classroom. Opsec concerns aside, that seems more reasonable, doesn't bother adults or anyone outside the country.
A school-based ban does indeed seem like the best option, even though it doesn't fully address the problem.
Putting this on parents alone might not be the right approach, individual parents can't fight a billion dollar industry that specifically designs their applications with armies of specialists to get children addicted to devices and applications. (Which of course doesn't relieve the parents of their responsibilities either.)
