don't live in the city with the commie nannie statists, in fact live so far from the nearest school you can easily be allowed to homeschool them

and then go walking with them everywhere

that diagram in the article is horrifying to me, i am only born mid 70s and i many times walked 5km or more, at age 10 i was visiting friends 10km away and spending all day on weekends riding my skateboard everywhere

my range was more like the great grandfathers, and my mother was not a latch key mother either... and she would go on big walks with us sometimes too, and sometimes we would go out to visit friends out in the country and on their big farms roam wherever we wanted to basically 

 Agreed, except for the "don't live in the city" part.

I will continue to beat on this drum—moving out into rural areas simply isn't realistic for many, or even most people, for a variety of reasons.

That said, most suburbs are pretty safe.  Get to know your neighbors so they'll recognize your kids when they're out playing or exploring on their own.  It's isolation that is the problem. 

 yeah, if your work requires your physical presence, sure, but people need similar work done out in the country too

the more people per square kilometer the more likely there is to be a psychopath near you and the easier and cheaper it is for the government to abuse you

if the target audience for this is normies, sure, but if it's bitcoiners or nostriches i think they need to understand that you can live away from the cities in most professions if you have got a bit stacked to take the leap and weather the startup process 

 Bitcoiners and Nostriches are, frankly, elites by broad standards.  Many are knowledge workers who can work remotely with a good Internet connection, and many others are homesteaders or otherwise interested in self-sufficiency.  That's far from the middle of the population bell curve, by any standard.

As you said, if that's the target audience, then yeah, you can move out of the cities.  But that's a small fraction of the population at large.
