If that's what you want, cool, you almost certainly can find a life situation where it's possible. It's people who want to forcibly make everyone live that way that are the problem.

Yeah to re-make public spaces across the cities and towns in that image would require probably a 10s to 100s of trillions in infrastructure spending. Enough to make my personal dream of an aqueduct in to the southwest from the Pacific and associated desalination projects (and mineral separation) a pittance.

We already spent trillions bulldozing cities for cars and building speedways everywhere.

"you almost certainly can find a life situation where it's possible"

The opposite, really. Car-dependence is the default and being able to live well without a car, especially as a family, is very challenging. Sadly we've forcibly made everyone live that way (imagine that!) except for the few who can afford well designed places.
