That brings some weird factors into play. If I'm slightly more qualified to work a job than another candidate, but I live across town and the next best guy lives down the street, it'll be hard to justify choosing me over a factor unrelated to my performance.

Also, what if I move way into the country or the next major city over? (I live in Denver, and it's not uncommon for people to commute from Colorado Springs). If that adds 2+ hours of daily round trip commuting to my day over something that was 100% my choice, it's not really fair to the employer either. I'm not a "think about the businesses" type normally, but that is kinda BS for someone to make a decision that increases someone else's costs (or decreases their output) by 25%
