SpaceX has a very, very large financial interest in avoiding collisions. Providing this service helps ensure that.

Several governments have an even bigger interest in avoiding these collisions, so, these systems should have existed for decades now.

But, you can always trust the government to spend 10x more to do 10x worst...

    Dubious. Perhaps if Congress could be persuaded to invest in tons of radio telescopes / radars, positioned all around the world, but good luck with that. The space-based approach used by SpaceX is something that presently only SpaceX is equipped to implement. Tracking star conjunctions only gives you high quality data on space debris / satellite maneuvers if you have a huge net of star trackers in orbit, and that's something which only SpaceX has been able to do.
