Cars are the only way to get to most markets. And the largest markets today are invisible because they operate online & operate almost entirely via motor vehicle deliveries.

Cars being the only way to get to most markets is a result of authoritarian policies. Cities that grew naturally before cars and Central Planning work better for people because they grew with freedom.
So you think there would be no market for cars if not for govt policy – this the same govt which originally tried to ban & cripple the market for cars?
You think people would rather just walk & carry shit everywhere? My neighborhood is great for walking & most people still drive golf carts everywhere.
