Nothing you wrote disproves the post to which you simplistically responded. In that post I said that Gunn had played down Mad Lib fantasies, and all you did was to prove my point. There's no "backdrop of colonialism" at all, such as appears in various contemporaneous Lib films; that would have undermined Gunn's flattering message about American Kindness. The fact that Gunn invokes legalities about whether an alien has rights at all is significant, though, because he wants to imply xenophobia without actually saying it. Instead, in the opening conference between Luthor and the American politicos, the latter are largely concerned that this super-powerful alien is interfering with their geopolitical aims, but they don't want to move against Superman because he's super-popular. Once Luthor conveniently finds something that supposedly makes all the good will the hero accrued just disappear, THEN the politicians give Luthor total control. Afterward, all we hear about the officials is Luthor complaining that he can't kill his captive right away because the officials want to question him, and he Luthor has to figure out some way to placate his theoretical superiors.
There's no indication of political pushback against the politicians in control. Where's the ACLU trying to defend Superman's constitutional right to a hearing? Where's the Liberal Media fussing about Superman's rights the way they have done with Abrego Garcia? All we get is the Daily Planet, but they're not investigating Superman's captivity because of his legal rights (though I could have missed some piddly little aside, given that I've only seen the flick once). Lane and Olsen have personal connections to the hero, so they believe in his goodness, and by implication the others share that view, and the view that Luthor is a dangerous scumbag.
Gunn even loads the responses of the other superheroes to Superman's captivity. Initially they don't want to move against the supposedly monolithic government, and as I recall Mister Terrific only helps Lois not because of Superman's personality or his rights, but because Terrific is leery of the dangers inherent in Luthor's pocket universe. So, if Superman had just been held in some real-world Gulag, I guess none of them would have done anything. What happens to make them decide to intervene against the Boravian aggression at the conclusion? That would be defying the government too. Gunn might have said something about how Luthor's messing with black holes placed the American politicos in a dubious position, and that the Justice Gang could do what they pleased because they the heroes had the politicians by the small and hairies. I'm not sure I'd credit Gunn with thinking things out that thoroughly, given all the plot holes he let stand. The original cut before pruning was four hours long, but I haven't seen any intimations about cut scenes like the hypothetical one I described.
