"Because they're the good guys and they care" just isn't good enough. And it doesn't do the film any good if the heroes care about them but the audience doesn't.
Gotta agree there. "Cause we're the good guys" just doesn't cut it for me with a lot of stories. Especially one as clearly wrong sided as INS.
I assume of course that you would
a.>Inform them they have to move
b.>Allow them to appeal via the courts
c.>compensate them
Are you native to this planet or star system? How many of you are there?
a.) . Waaa, you're six hundred people that accidentally reaped the rewards of the planet. I've got 6 billion-plus that need this planet. So either you let us land a colony on the planet or get Uhual on the line and pack your shit, it's moving day
b.) Want to appeal? Here, all 600 of you pile into this ship, we'll warp you back to Federation space and stand "guard" over the planet while you're gone.
c.) You want compensation? Well, I have 4 forward torp launchers, 200 torps, and a weapons officer that likes to blow shit up. Can you make change?
This is why I rarely think deeply about Trek movie.
