A. The Apollo moon orbiter & lander were not made of stainless steel, Starship is. Starship weight 100 tons dry weight. Super heavy booster dry weight 303 tons. Gross weight fueled for both is 5,000 tons. Starship is bigger and more powerful be far that Saturn V was.
B. No matter were you go there is always mass; the more mass, the more power it takes to move the mass.
C. Because StarShip has more mass than either Saturn or Artemis, it requires multiple refuelings to go to the moon and to return. Saturn V and Artemis use composite materials which are far lighter than Stainless Steel.
B. The more power it takes to *accelerate* the mass.
I think you missed my point.
