Or entirely new capabilities get developed. Look how long it took for the F9 Heavy to get any business because fitting payloads really only got planned and developed after it demonstrated its abilities. With the Starship, there will be single payloads of 100t or more - Elon is even talking about 200t in future versions. That is a total game changer. A station like the ISS could be set up much quicker. You could start designing real spaceships with e.g. ion drives. And a 100t payload might even cost less than currently a single F9 flight.
