So
rocket fuel cost on earth are rather small part of the cost of the rocket, and even though one is paying 75 times more for rocket fuel on the Moon it's equally a rather insignificant cost of the rocket launch per tonne or kg delivered to GEO.
The cost instead 5000 per kg to GEO and $ 8000 per kg to lunar surface, will instead $ 5000 plus
rocket fuel cost at lunar orbit [450 per kg] plus the use of a reusable spacecraft.
