This isn't true at all though. There's a small amount of areas that are able to be super expensive and you can walk to stuff. Then there's far more cheap areas where you can walk to stuff that aren't generally desirable. The slightly more expensive unwalkable areas are intentional because the only way to keep the area safe is to make it inhospitable for people who can't afford cars.

Allowing business also does the opposite to property values, it creates demand to sell because fewer people want to live adjacent to heavily trafficked areas.

There has to be a careful mix to have business and residential in the US and it not devolve into Vape Shops, lottery stores and other highly profitable but exploitative businesses.

It really only works if there's some other sort of barrier like general unaffordability.
