There should, in short, have been an entire small town/culture community aspect to the show, not just throwaway lines here and there when the rest of the shows are devoted to meeting the Random Humanoids of the Week. But the fact that none of the main cast, to my knowledge, ever seriously dates anyone outside of the opening credits-named regulars speaks volume about the small-mindedness with which the series was plotted.
That's because no one in the show, not the producers, not the writers, no one IN the show either (characters) ever believed they were going to be stuck in space for 75 years. No one.
And given how whenever something like this happened to other Starships (Kirk and Picard) and they always made it home with no worries, they had every right to feel that way.
What they needed to do was have Janeway make mention of how this has happened before to other crews and they always made it back, and thus the VOY crew have no reason to think they won't make it home in less than 75 years.
This isn't like Battlestar Galactica where the crew are all that remain of civilization. Voyager was just one ship in a galaxy they KNOW is full of wormholes or super-powered FTLs or beings of vast power that can send ships anywhere, etc. This whole "Community in space" thing wouldn't make any sense, nor would it make any sense that folks resigned to thinking they weren't going to make it home wouldn't just ask to leave so they could settle some random planet.
