Although it's an important discovery, the real importance lies on finding water on objects that we may one day need to live on. We're never going to set up facilities on an asteroid. But on a moon we certainly could, and finding water ice there would be significantly more revelatory.
By that logic, Galileo and other early astronomers who sought to explore space and discover distant planets were wasting their time. Since at that point in history getting into space was barely conceivable.
Exploration for the sake of exploration may seem pointless to you now, but knowledge about our universe is beneficial to the human race.
