Hey, @bashadow.
After the fact, when there's not much anyone can do about it.
Yeah, I agree. Of course, most crew members on a Federation Starship seem like folks you might want to have their back because they would reciprocate. And in such a case, the needs of the one would probably be met, regardless, except in those extreme circumstances requiring the ultimate sacrifice. But that wouldn't come after years and years of sacrificing everything else, because that wouldn't be required.
So, it might have its place in such a world, but not here. Not now. Such a thing would lead back to communism, or some other form of totalitarianism disguised as best for the working class.
