This is a really naive take. I tried literally what you’re advocating. And what happened was some busybody lady in my neighborhood kept calling CPS when my daughter would walk to play at a friend’s houses down the block. When I was her age (6) I ranged an entire town on my bike. But this lady just kept calling on us. She’d bring my daughter home whenever she saw her out. It was infuriating. Once we got the Apple Watch the calls and helicopter stuff stopped. Also, the GPS tracking on the cellular Apple Watch isn’t even super accurate, but I can call her to let her know it’s time to come home.
The other kids seemed to have followed suit, their parents relented (mostly, the Muslim families on our block seem to keep a very tight leash on their kids) and run around the neighborhood freely. But before our kid started going out nobody was going out.
