A numbers-driven look at whether reusable rockets actually changed launch economics. The cost structure of expendable versus reusable vehicles, Falcon 9's list price versus its internal cost-to-fly, the cadence argument, Starship's full-reusability case as promise versus demonstrated reality, and the $/kg-to-LEO curve from Shuttle to today. Skeptical throughout: list price is not cost, and a target is not a flight.
