You're spot on. It just isn't really necessary to refactor Clojure code. In my many years using it professionally, I didn't have to refactor it once. The code just stays clean, it doesn't need cleaning up. So I find the whole refactoring argument moot. Why does your language lend itself to code that needs to be refactored? Sounds like a disadvantage to me.
