Possibly even, aspects of smartphone use should be treated as a potential health risk, in the same ways as alcohol, tobacco, sugar, etc. (though not all of those are treated appropriately yet)
I think most people who have trouble getting on and sticking with a keto diet are more addicted to easy-access food variety rather than particular foods. They'll succumb to the easy-to-order pizza delivery in larger part due to its easy-to-order and being-something-different properties rather than the craving for pizza/sugar itself being too strong. Keto is easy if you don't mind the monotony of the same easy-access food for almost every meal, or enjoy cooking enough to make a large variety of food. If you do mind, that'll probably have to go first, sugar or no sugar.

With regards to children in school we need to just start early and teach them that not using one in class is being courteous to their teachers and others while at the same time perhaps offering them more time between classes to check their phones. It is just a matter of showing them how it should be done and rewarding proper behavior.
This one is lighter in the way that now, the phone can be used outside teaching hours (so between lessons) and on certain events (like museum visits or sports event during school time)
And as always in France, it’s a law above a law above another law, etc...
But French president Macron was very proud of it, so bravo...
My guess is that 1) most teachers have no idea how to teach using smartphones, and 2) the new digital economy is threatening the job of teachers.
