I mean, this map (as any) has a lot of problems. The most obvious ones in my view are "How is Wyoming part of the Great Plains and not the Inland West" and "How is all of Indiana urban in the same way that Chicago is"?

But the bigger problem is twofold. First, you don't have to <redraw state lines> to do this, and it seems like a lot of HN commenters feel that redrawing states is the best approach. Second, due to Republicans who hate all government and Democrats who view all "urban planning" as inherently racist, there's no real possibility of a consensus to have any plan at all to improve American cities as a whole.
