>Assuming rocket launch demand continues to grow exponentially
The issue here is the market doesn't know where we are on the S curve. If we've looking at space shuttle prices, we are at the end of the curve. If SpaceX pulls off reusability with the starship, then I'm going to make guesses we are much lower on the curve then most expect.
If they can get 'cheap' launches of 100-200T to orbit then a massive number of new possibilities open up and SpaceX won't sit around as just a cheap transport monopoly, they expand horizontally into other space based markets.
