The school I work at is implementing this starting next week.
Except it's a music school so they can use metronome apps. Also, they can use it to send emails to the copy room to print music sheets. Or to use in class when it's required. Or for whatever exception they can think of. And they actually expect us to enforce it with all these exceptions.
No, it's "better" to source materials for education from the students themselves. In the US, good luck learning if you don't have the mandated school supplies. I'm sure if we didn't need the state-sponsored daycare so adults can work, the administration would rather have all students be virtual.
