There is a huge gap between "not frictionless" and "impossible". Sometimes, people have to make hard choices. The reality is that if you want to live in a trendy/convenient/nice part of a major city, then you will have to pay for it, because EVERYONE wants to live there.

Sometimes, you just can't have everything you want.

It's not just the trendy parts. Eventually even nearby suburbs become very expensive. Yuppies are not moving to KC, they're pushing the poorest city residents further and further away from the city. It's fantasy to think it's the relatively well-off who will have to move, or that the poor people who are being displaced have that much mobility. Just look at all the people trapped in economically depressed rural areas, why don't they all "just move"? Lots of Americans have literally no savings and very little job mobility and moving a long distance is pretty much impossible.
