Which as the person you're replying to is point out isn't really a fair comparison because Starship and Saturn V deliver vastly different amounts of mass to and from the moon despite the mission being only to ferry some people there for a few days.

If Starship ends up flying to the moon it effectively enables the landing of a lunar base that could be occupied for years at a time with sufficient resupply of food and the right equipment for extraction of water/oxygen from the moon.

The Saturn V as amazing as it was could never have brought that much equipment to the moon in a cost effective manner.

Second, SpaceX has consistently shown lower development cost then anybody else. Starship is expensive its likely cheaper then New Glenn.

Remember, Ariane 6, a marginal upgrade over Ariane 5 with only a new upper stage engine cost 6 billion $.

And SpaceX is already at much higher launch rates and manufacturing rates for thing like engines. SpaceX is investing into mass production already.
