That's a good point. I think this contrast between individual (often flawed) human judgment vs collectivist ideals has always been a theme. In TOS, you see Kirk calming McCoy's knee-jerk reactions almost every episode. In TNG, it was Yar or Worf. In DS9, probably Kira.

Even then, I would say the collectivist ideals (i.e. Starfleet regulations) were more often portrayed as overly-cumbersome in implementation, which leads to someone like Kirk violating the rules in place of the ideals that they stand for. For example, how many naïve (but well-meaning) diplomats do we see in TOS or TNG? However, rules being restrictive or imperfect in an effort to support larger agreed-upon morals can still be trusted, compared to corrupt power structures, which cannot.
