Kids have learned to walk places on their own without maps or satnav or tracking for hundreds of thousands of years. I believe everyone would benefit from that continuing. We don't teach kids that the only way to do arithmetic is with a calculator... they learn first, then get a tool that can support what they already know. Why do we think we should do it differently here, and train this learned helplessness without a phone glued to your hand. I suspect a lot of this is projection of the parents' own discomfort with being away from their phone.
Parenting is hard. Parenting when everything is changing so quickly is very difficult.
Parenting is also a strictly optional hard-mode that you choose to switch on knowing full well there's an 18 year cooldown before you can switch it off again.
So, Find My is invaluable for locating it again.
