South Korea built a new capital but most everyone there still tries to live in Seoul. There are very affordable cities in upstate New York within a few hours of New York City that are still losing population. This concentration in winner cities might swamp efforts to lower prices with new cities. Arguably the Sunbelt suburban cities are new cities. If 90% of a metro's population is new since 1945, that's a new city grafted onto an old town. In the US at least, we have built new cities, and we have also crowded into a smaller number of winner cities. Canada, despite being huge, actually has fewer opportunities for new cities because building on the Canadian shield is impractical.
