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.
