Well, right now if you want to move quickly and often, the hassle of moving in and out often makes it not worth it to mobilize, and hence you choose not to take a job that is somewhere else but utilizes your skills more effectively (allows you to produce more output in economic terms).

Don't know if a good solution exists... housing is a very messy optimization process because people want vastly different things in their homes. I guess you could focus on niche groups so you can get some standardization going.
