Let’s not think of all the infrastructure to get what they sell to the people who buy it or that gets the stuff you buy to you. And if your response is, “Well, that’s only 100 miles to the nearest store/city/hospital,” that completely ignores how the stuff got there so you could pick it up.

Unless your lifestyle is such that you only have to buy or sell things a few times per year to survive, you’re relying on that national/global infrastructure to enjoy your rugged, individualistic lifestyle.
