All your arguments are basically circular- Kirk would do it because it's the "right thing to do." Ru'afo has to be wrong because the film has declared that he's supposed to be the bad guy. Sorry, I don't find those persuasive. Permanently defending a tiny village of pacifists who are such hypocrites that they'll let others fight for them but won't do it themselves, and didn't tell anyone else about a revolutionary discovery because it would have spoiled their private little Eden is not "the right thing to do." It would also be blatantly picking sides in a dispute where the Son'a have equal claim to the planet, so in addition to being strategically foolish during a time of war, it's a violation of the PD as well. You're asking the Federation to violate its own laws and sabotage its own war effort to help a small village that contributes nothing to the Federation.
