This isn’t true. A business owner completes tasks with the help of employees, but unless he is indebted to a lender, he is still ordinarily thought of as being independent. Independence is a spectrum, and people who require that the world be re-engineered so that they can access it are generally on the lower end of that spectrum.
> The difference between their dependence and mine is not that mine exists. It is that mine is visible. […] A person who drives to the grocery store is considered independent, although the car depends on fuel, roads, mechanics, insurance, and a global manufacturing network. A person who orders groceries because they cannot walk through the store may be considered dependent.
The author is conflating two kinds of dependence. Lots of people rely on food delivery. If a food delivery system breaks down, it could be an existential threat to both parties, the difference is that the able-bodied will tend to have a greater level of optionality in how they respond to this kind of breakdown.
Someone suffering from kidney failure is obviously more dependent on the supply chain than someone who is not suffering from kidney failure. There is a debate to be had about how much this gradation matters if both categories of people are still mortally dependent on a system; am I independent if I can cross the street by myself but don’t know how to grow enough food to feed myself?
