A lot of those are problems caused by phones regardless of whether one uses one themselves.
But for the personal ones, there are self aware addicts of all kinds. Smokers know cigarettes are killing them, complain about them, sometimes even hate them but can’t stop.

That’s a fair and well measured response. It begs the question of what we can do as individuals, and when it comes to smart phones I don’t think there’s much.
