Well, if you set your series on a starship you probably don't intend to show its crew just hanging out at home half the time. I mean, I don't complain about Westerns not including enough Austro-Hungarian court intrigue either even though both take place at the same time on the same single planet.
Which, by all accounts was Dave999's point. He referred to something as "Like Star Trek on Earth," as an analogy for a setup unfriendly for adventure plots. You appear to be agreeing with that analysis, yet still for some reason seem to be implying that he stated something erroneous or untoward, and the rest of us are unclear why.
