But Falcon 9 also took a long time because it doesn't launch all that often and SpaceX had a lot to learn about how to work with NASA. The "idea" of Starship / Superheavy is that the same first and second stage can get caught by the landing tower "chopsticks", have a crane re-mate them, fuel them, and relaunch them within 24 hours or less. If they can relaunch the same entire stack more than say 2 times per day, they're going to absolutely hit the reliability margins[1] that NASA / the FAA want to see in a very short time period.

The overall mission loss risk, which includes vehicle risk from micrometeorites and orbital debris while in orbit for up to 210 days, is required to be no more than 1 in 270.[3] Maximum sustained acceleration is limited to 3 g.
