Artistic integrity usually implies someone cares about their work and isn't in it purely for profit.In pop entertainment, that's never anything other than "What I like and think is cool."
Pop culture has always been a combination of the creative and the commerce. Many who've worked in that system have been passionate, talented, and sometimes profitable. Only one of those terms fits Alex.
I'm not asking for complete realism.Starfleet is, without question, a military organization within the stories. Nonetheless, it's been flunking basic tests of plausibilty as a navy since the day of its inception. Virtually all of its Starfleet characters who show any volition in the stories would end their careers in disgrace and, most likely, military prison.
Trek has as much plausibility as you decide to grant it. No more.
