Earlier quoted context omitted.
I like trains but the logic is flawed. If we banned hats, or made it so they were very expensive, less people would wear hats. And sure, probably more places would worry about shade because hats are not an option... But it doesn't really prove that's the right thing to do or that hats are inefficient use of cloth.
Hats are pretty objectively an ineffecient use of cloth, here. Roads are incredibly expensive to maintain societally because cars cause so much wear-and-tear; cars, maintenance, and insurance are expensive on the individual; lack of foot-traffic is expensive for business-owners; individual car-use is much more expensive on the planet and power grid; travel is more difficult & and dangerous for children and old-folks……
Actually the wear and tear due to cars is minimal compared to that of trucks. The relationship of wear to mass is nonlinear. Which isn't to say that buttering half the earth with asphalt isn't a seemingly absurd use of resources.
