Walking is NOT free. There are the calories you must expend to do it,


This is actually a negative cost, offsetting the other things you mentioned. People usually PAY nowadays to get rid of calories.
Need to add the wear and tear on shoes to your list though.

That depends on whether you view the expending of calories as a cost or a benefit (as you call it, a "negative cost"). If you're an overweight suburbanite trying to take off some pounds on the jogging path, that's one thing. But to, say, a villager in Kenya walking a couple of miles to fetch water, the walking has a definite cost in terms of energy expenditure.

And for both persons, walking carries an opportunity cost: time spent doing it cannot be spent on other endeavors. This is why most people in Western countries don't walk when there's a viable alternative: it's too time-consuming.
