In the US you sometimes hear that phones in class are necessary to see if your kids are OK in a school shooting scenario.
I think this isn’t a good argument, since school shootings are rare, and it’s unclear if each student having a phone would do more harm than good in that kind of situation.
They did this in California and Oregon, then the schools went to shit.
Also, property taxes are a good way to encourage density, which is necessary to fight climate change
