While I think the comment you were responding to was being somewhat snarky, urban design specifically to accommodate walkability is a thing. Cities that are high-density and mixed-use allow for many of the things people need to do on a daily basis to be close to where they already are, which makes "around" smaller for most purposes and consequently makes "quickly" more achievable on foot. Cities that have lots of parking lots place the actual stuff people want to visit farther apart, or who entirely separate offices from retail from food from residential, require vehicles.
