You are using the historical trajectory of rockets in a way to prove your point :) But looking precisely at rockets, there was a boom in technology where the distances and velocities we could go increased exponentially until the tech matured, and now it's settled and still pretty expensive to go up there. In fact, this trend seems common with technologies (rapid growth until a wall is reached). I wish I had a link to the graphs I have in mind that make this argument.
