Something that I rarely see mentioned about SpaceX's goals and financial viability of a reusable Starship is how significant of a boost they get to their talent pool by working on the absolute bleeding edge on things that seem impossible. People go work at SpaceX because they work on crazy things like Starship instead of only working to make "cheap flights for satellite missions". SpaceX attracts the absolute cream of the crop (at below market rates even but that's besides the point) and those people work better/harder than they ever would working on more boring goals. It's the power of vision and motivation.
