Saying something has no replay value because you don't want to replay it doesn't really make any sense.
Replay value is literally how much people want to play the game again after beating it
Starbound's content ends in a few hours of raw gameplay. After you've seen everything, there's no reason to look for procedural generated content because you've already seen it all after seeing all the different world types
the developers, instead of developing raw gameplay, keep stuffing in empty content like collect-a-thon garbage and pointless, roundabout quests for the sake of quests
there's no meaningful content inbetween all the filler and it ends up being a good experience until you run out of things to see
