Could they use a circular lift that loads ballast at the same rate as they unload cargo, the way usually proposed for a space elevator? That would at least solve the ballast problem and lift problem (while still needing a solution to keep the airship in place horizontally AND needing tough materials for the lift).
Or one could stick with the existing transport solutions: sea, air, rivers, truck and rail. Those work just fine to get basically everything anywhere on the planet.
