"This is outrageous. Where are the leaders who come in to cancel these one-off, expendable vehicles? Where are they? These kind of designs are never tolerated at SpaceX. You need an Earth-orbit departure stage? Starship. Right away. No question, no nothing. Lunar lander, we have a special Starship for lunar lander. Mars cargo lander? Starship. Crewed Mars transfer vehicle? Starship. Crewed Mars lander? Also Starship. Mars ascent vehicle? Starship. You are charging too high prices for... SLS... mobile launch tower? Right to Starship. Earth return vehicle? Believe it or not, Starship. We have the best launch vehicle in the world... because of Starship."
