The problem I have with teleportation is that it seems we're closer to being reference types than value types, so I'm not sure a rebuilding in situ would work for the cases we care about. For static objects, I'm not sure how you'd get past the constraint that at some point you want mass somewhere else, and it needs to be moved.
