A lot of established cities today were planned shortly after founding. They were just planned with a grid pattern conducive to the flow of traffic from carriages, streetcars, or railroads rather than pedestrians. It's completely reasonable to plan a new city today with the goal of being walkable. Given the fact that so many of our most valuable cities are navigable without a car, it seems that there may be a strong economic incentive for such cities, just no one has really tried to capitalize on it. We are seeing a lot of walkable microtowns popping up around the USA, but these are more centered around renters than owners. Which might be due to zoning issues than market forces.
