EDIT: I'll clarify. You refer to safety. I grew up in a place where being outside as a teenager was perfectly safe, also at night. I want the same for my kids, and it's totally achievable. I think the whole idea that the world is somehow "unsafe" and that the parents need to constantly helicopter to guard their offspring from all the evil pedos and thieves and lunatics, is a fundamentally harmful idea.
Now, I do recognize that America is pretty scary, with their gun laws ensuring that either a gang member of a cop can shoot you dead on the spot if you dare take a snickers out of your pocket while they see it, but not all places are like that. Iceland sure isn't.
There's no good reason, in affluent places at least, for "the outside" to be dangerous. And if it is then that's the problem that needs to be addressed, not parents who want to allow their kids to learn their own life lessons.
I think this article has plenty good ideas but I don't think legally enforced helicopter parenting is one of them.
