If there are considerations that allow comparing alternative desires, and ways of influencing which ones you get, it may be a mistake to keep suboptimal desires. “They are just desires” stops the potentially fruitful inquiry. Desires are part of the world, subject to optimization.

In general desires by themselves aren’t rational or irrational they are just desires.
