You seem to be missing the point. In the vast majority of cases locations being unsuitable for walking/cycling to school isn't an immutable law of nature - it's a result of deliberate choices made by humans.
Building primarily low-density car-dependent suburbs is a choice. Building horribly oversized car infrastructure is a choice. Not building bike or pedestrian infrastructure is a choice. Building one megaschool instead of a handful of smaller local schools is a choice.
People voted to have slightly lower taxes and spend a few hours a week waiting in the pickup line. That's a lifestyle choice, even if they weren't aware they were making it.
