> This is possible if you’re not picky about where you live, where you work, your career options, how crowded your local vicinity is, or how much you pay for your residence.

Perhaps the problem is the lack of options for those people that want human-centric (versus car-centric) communities. Maybe if we let The Market™ decide, versus forcing low-density sprawl via zoning, more options would be available.

Right now, if you look on any real estate web site, you'll probably find walkable neighbourhoods have higher prices non-walkable ones: there is demand for them, but a fixed supply since they're not being made anymore, and so they get bid up. Perhaps if there were more of them, especially around commuter rail stations, it would help.
