You mean, not very much? Everything about space-based anything is dependent in the short to medium term on Starship making mass to LEO cost about as much as air freight.

Starship, at least as a rapidly reusable second stage, may fail, rockets are hard. But you aren’t really engaging with people’s dreams if you start from “we don’t have access to the technologies that appear to represent a one to two order of magnitude cost shift”.
