They say they want to be able to walk to places more. But they also want a big suburban-style house with bedrooms for everyone and storage and garage and lawn etc, easy parking for them, nice wide roads to drive everywhere on and tons of free parking when they get there. This makes it impossible for the area to be walkable unless everyone else lives in small apartments and there's actually only enough parking for just them to drive if they feel like it.
In my opinion, it doesn't work that way. Yeah everyone wants to be the special 1% like that, but only actually 1% will be. If you really want to be walkable, you personally will need to live like that too.
Pretty much everywhere has a political majority of single-family homeowners, and if each locality decides on its own it doesn't want to have multifamily housing, then you wind up in a situation where almost nowhere actually allows it.
