"Walkable cities" doesn't mean that everyone is forced to walk everywhere. It means that there are destinations (grocery store, restaurant, pub, library, cinema, hospital etc) you can reach within walking distance without having to play frogger on a highway. They are absolutely a boon to someone old and disabled. They can use assistive devices, public transport, and even cars to get around.

I think you have the wrong impression about what "walkable cities" mean.
