Any progress on "Mars vanity projects" directly helps the project of colossal space telescopes. The reason the James Webb Telescope is so expensive is because old spaceships didn't have enough cargo volume to hold the telescope unfolded, so they had to create an incredibly expensive and error-prone unfolding mechanism. SpaceX's Starship is big enough to hold the JWT unfolded - something that would dramatically lower costs on any future telescope of the same size or bigger.
