Well, that 's an example of what people are talking about here. _You're_ excited about the idea of colonizing another world, but other people aren't.
The prevailing attitude is "fix the problems here first". But that's not my attitude. My attitude is that SpaceX's work is important because cheap access to space opens up new possibilities. I'm not excited about colonizing Mars itself, and I'm not really that excited about the Mars mission because I think that solving challenges on a hostile, empty planet wouldn't translate that well into the best solutions for a more friendly planet, particularly for densely-populated areas.
To me StarLink represents a clear benefit of cheap launches, and the impact would be more than just a different communications network. It represents the ability to avoid the market barriers that lead to local monopolies and oligopolies and to enable good telecoms _everywhere_ at low cost.
