Right now the situation in the world is crazy and there is no easy solution to any problem.
The other point is that parents and guardians have to very carefully protect their defenseless children because the world is so dangerous - bad dogs and bad people.
When I was a kid I wandered by myself all over rural (mostly) and suburban (one year) neighborhoods, went for hikes, long bike rides, by myself or with another kid or two. No problem. I would never allow children to do that now.
