On a more serious note, if you get the infrastructure going to get a lot of hardware and people to Mars, then getting some more modern space observatories should be quite easy.
Do you have proof that Starlink profits will go towards funding a Mars colony? Or that research into astronomical observations will be required for building a space colony? Or even if so, the overlap somehow helps astronomers on earth?
Funding transportation to Mars to enable establishing the colony, and the question should be, do you have evidence this is not the case? Because this was what Musk/SpaceX have been saying since Starlink was barely an idea, and I haven't seen anyone prove they're lying.
And to the shareholders. Who may choose to build casinos in the desert with that money.

It's more accurate to say it will give us access to space views from space at the highest cost that the market will bear. I assure you this cost will be well above what 95% of the world will be able to afford for quite some time. After all, much of the world can't even afford regular flight.
There's a reason SpaceX isn't public, and it's precisely that. Starlink was, since its conception, and still is, a way to fund the R&D for opening access to Mars.
It's not like the funds from Starlink are going to be used to build casinos in the desert or something. Every $ earned is going back into building better space tech. So if it fails no problem for space views from Earth, and if it succeeds the result is cheap access to space views from space.
