Agreed. If we truly wanted them we would be willing to give up car ownership, single family homes, and suburban sprawl. I doubt that will ever happen in this hyper-individualistic culture. Hopefully it is uncontroversial by now to say that an enormous swath of American society does not believe in self-sacrifice.
I think you are dismissing or not considering a major part of living in a walkable area - the cost of housing at any square footage. I know I did until quite recently.
I really want to live in a walkable city, and would be thrilled not to own a car and live in a smaller space. I'm a remote dev, and as my partner just finished graduate school and is starting their professional career I thought we'd have the perfect opportunity to live the dream and move somewhere where we could use walking/biking as our primary form of transportation.
Turns out, there's a very limited supply of walkable communities in the US and they have a significant premium. We gotta pay off graduate school loans and even with higher salaries, it would be years of additional repayments living in somewhere like Seattle or New York vs a suburb of Raleigh, NC. There are small and more out of the way walkable communities, but not really any with good job prospects. Maybe at some point in the future, but right now I honestly don't think I can afford it.
I would love to give all that up. But until change happens, I can't. It's a chicken-and-egg problem. I believe many would give that up if they could, especially younger people, but there's no option to give it up currently.
