Yup, came to say this.

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.

Give your kid some quarters so they can call you on a pay phone like the old days.

As a parent I want a phone I can find because kids will lose a phone.

So, Find My is invaluable for locating it again.

The kid doesn't need it, but the parents need the kid to have it on him to appease the bored onlookers one digit away from calling the authorities.
