Is this something we have evidence for, or is this just in theory?

SpaceX built the biggest constellation to date, and is using the profits to build Falcons while designing Starships. Check out the resulting cost per kilo to orbit:

That's pretty good for theory.

The theoretical part is whether that's actually useful for not. Cost per kilo to orbit doesn't magically solve astronomical observation problems.
