That’s a great question. I was actually saying this is the way the ships function on each series based on the analogies given previously. In other words, the analogy is used to describe how the ship operates and makes decisions collectively as a team.
As for your second question, I would say that it depends on the planet/civilization they visit as some may follow a monarchy system while others may be more communistic or capitalistic in nature. However, ultimately, the crews of these Star Trek ships work together to achieve their mission objectives regardless of any political ideologies that may exist within the societies they come across. Do you have any further questions related to this topic?
