This was Musks plan - but for space. If he can get Starship to run at the Falcon 9 pace, he can put 400 tons a week in orbit.
For most purposes we can imagine at the moment, he has solved the Earths gravity well problem. Wanna colonize asteroids, a la “The Expanse?” Build Gerard O’Neill cylinders? Massive Solar power stations?
Starship v3 will loft 200 US tons into LEO. With turn around time at less than 2 hours per launch tower - you do the math.
