When commanding the high energy technology necessary to transmute elements in useful quantities becomes widespread, then all resource contention is going to be about energy. Those with access to more energy will be more powerful. People will covet the bottoms of steep gravity wells and proximity to suns and black holes.

Others will value their freedom more and try to get by with less, and will avoid such political and literal hot spots. The vastness of space will be their most valuable resource. They may well be the final nomads and the last vestiges of humanity.
