I don't think capitalism is the problem here, it's government policies. Zoning codes which only permit low density development and require parking spaces encourage car centrism, and all the problems you mentioned. If these codes were changed to allow for more density and no parking minimums, the free market would be free to determine the optimum density and required parking for an area.
