Sure, the tiniest kids are on the show because it's funny and adorable but it doesn't really change the general point. I've lived in Tokyo and you see elementary school aged kids 6, 7 years old alone all the damn time. When I was in elementary school I was off on my bike every day. This is normal in much of the world. And there weren't any trackers. And that's actually important, because being on your own without the safety net is what builds confidence.
