>The thing is it just doesn’t seem like the average person is willing to give up single family houses to gain walkability.
As other comments have mentioned, you can have both. In addition to that, the reason that people choose single family-houses is not necessarily entirely by preference: almost all of the land zoned for housing in the U.S is zoned for single family-homes. Add onto that some arcane rules about minimum parking amounts, minimum setbacks from the street, and the fully absurd standard to which suburban streets are created (too wide, essentially mini-highways), and you get the mess that exists right now.
By addressing these problems, you'll go a long way to improve walkability.
