Oh, I know quite well how bad internet and mobile coverage can be outside metropolitan areas. All those areas so, well the vast majority, can be supported by terrestrial internet using either 5G or fibre. SpaceX has thus to be cheaper than those terrestrial solutions in order to compete.

Markets where satelite based solution are the only option include maritime, desaster areas, aviation and remote areas without inhabitants. Everything else, Starlink competes with, e.g., 5G. Just how competitive Starlink is, nobody outside SpaceX knows for a lack financial data. And since the use of reusable rockets only got traction when SpaceX created in-house demand for them, well, I am sceptical regarding the economic viability of it.

As I said, it can be typical Musk goal post moving, a viable business idea or a combination of those two. And by the way, Uber was cheaper than Taxis for a long time by selling a dollar for cents, and the same as Uber SpaceX has access to capital other ISPs just don't have. Doesn't mean SpaceX ia serving a market, remote areas, existing ISP are neglecting for decades by now.
