You treat the walk as the default and car as something that needs to be justified. That's BS. I think you are too privileged to live in a safe neighborhood, in good climate, to be healthy enough to walk with load, and to own a good backpack :P
To me car is the default solution, it's simply better in every way for most people. Making one's life better doesn't need to be "justified".
It is! Just like not having surgery, not using AC/heating, or not wearing glasses, etc. All those things are unnatural and some are expensive, but luckily we are not hunter-gatherers anymore ;)
