I see your point. You're saying the sun and moon are actually a star and satellite, and calling them the sun and moon isn't bad. Could I then assume you would feel the same way I do if we called the sun 'the star', and the moon 'the satellite'?
The one problem I have with that argument is that you basically take a broader term, in this case star and satellite, when in fact they mean the same thing. A sun is a star. At least that's how I've heard it used, though I suppose using it in the place of 'star' came from the name of our sun rather than the name of our sun coming from the term for a star... If that makes any sense. While I suppose this does support the sun, it doesn't work with the moon as I'm fairly sure there has never been another general name for the other natural satellites of the universe.
I still think luna would be a better term for the moon. Titan and Io and all those other moons get their own names, I don't see why ours should be so special (only calling them 'satellites' would also solve the problem, as we are no longer giving our one a preferential title (saying the moon is a satellite, and Titan is a satellite... Rather than the moon is a moon, and Titan is a moon), but most people already feel most comfortable with moon).
In conclusion to my fairly dodgy argument I would also like to point out that luna and sol are much cooler. In my opinion.
But Sol and Luna are just the Latin translation of sun and star, so you are still essentially calling our systems star and our planets satellite sun and moon, only in a different language. So in actuality your reasoning still doesn't stand up because you are still using the words sun and moon only in a different language.
Yes, other planets moons have names, but these names are not just literal translations of moon, they are names scientist (I assume) chose to call them. Titan comes from the Greek mythology of the Titans, and Io I believe is a Greek god, so if we were to give our moon a new name then it would make more sense to call it Zeus or Odin or some form of ancient mythology deity names.
There are multiple natural satellites in the universe, however moon is the generic term that we have given them (natural satellite being the scientific name). Technically a car is an automobile/vehicle, yet you see many people still say "this is my car, that is their car", most people just say, "that planet has moon/s". I bet you that if you asked a random person on the street to name Saturn's or Jupiter's moons' they wouldn't have a clue what they're called. So in the end there is relatively no conclusion, presumption, or proof that suggests calling our star "sun" and satellite "moon" causes people to believe that the universe centres around Earth.
