You do remember that they signed a contract with NASA to have a lunar lander ready this year, right? A lander that requires more than a few launches and reuse of both the first stage and tanker Starships?

These launches are less about iteration than they are marketing. They are burning money and need to maintain interest in their magic Starship. They need just as many years as NASA and they need NASA's money. The difference is, SpaceX have not demonstrated they can achieve their technical goals and they gloss over all the challenges while at the same time they waste money and Raptor engines on these publicity flights.

Remember, Falcon 9 was earning them money while they experimented with landing. And they hyped up its capabilities and cost before eventually under delivering. Starship will be different in that it may not even male them money.
