in cyber space and paper planning visionary modeling one can certainly make rearrangements more easily than IRL. the Earth turns so there's no reason why various parts of Earth wouldn't be mobile as well. just takes a will and that will needs be practical to be efficient/economical. so get an inventory of what you have to work with, then come up with the best use of the land and somehow include potentials from neighboring lands in due time as well as a rating system for how difficult relocation of some aspects are. compost heaps are easy to move. buildings, bridges and paved roads, not so much. but with mobile buildings/bridges that doesn't have to be the case.

makes me think that using mobile aspects is best when a total inventory hasn't been done to establish best locations. then replacement with permanent structures and let new people use the mobile items as hand me downs to get them started.
