Micro optimizing your way to building 17 upper stages of Falcon 9 in a month in order to sell launch capability at the Falcon 9 price is a pretty valuable goal.

Micro optimizing your way to building 17 upper stages of Falcon 9 in a month in order to sell launch capability at the Falcon 9 price is a pretty valuable goal. It's also a better application of iterative development, on a stable base, with a small number of changes at each increment. They don't mask bugs and create more issues than were solved. It's not just that Starship is the wrong idea. It's the wrong idea developed wrong. It's very similar to cyber truck that way for similar reasons.
