Yeah like the other commenter said this isn’t it, nobody is commuting up and down 10,000’ on a regular basis, especially in antiquity. Just because different elevations “look close” on a map means nothing.
Far more likely is this is a concentrated population of folks with highly desirable traits for distance running.
I’ve come to realize most of the privacy hawk arguments are based on imagined risks, and the average privacy enthusiast is an ideologically driven idealist. What is the end goal beyond pumping one’s ego?
Especially internet privacy hawks are the worst. It just doesn’t really matter at all. Unless you are all cash, off the grid, no phone or bank account etc, you will leave a huge trail. Instagram figuring out I like basketball is the least of my worries.
