While yes, I agree Mars appears to have been Musk's long term goals:

> the gigantic Starship Factory and multiple launch pads under construction in Texas, Florida and Louisiana (plus potentially foreign countries) only make sense with Mars.

There's a few other things that also make sense as use-cases for that infrastructure. Orbital manufacturing is already starting to get interesting. I don't want to bet either way on space-based data centres, the research I've seen from Google says that makes sense at $200/kg which Starship can only reach if SpaceX solves re-use and that's clearly difficult but I don't want to say impossible.
