All that is only true until you have to reach to Java interop because of Clojure's lack of ecosystem of libraries. Since this is a necessity and fairly common, now you are back to this enormous OOP world of over-engineered libraries, eradicating all the benefits and joy a doing a project in Clojure, it's unfortunate.
Clojure is also not making this easier(interop) by not keeping up with Java advancements. Ex: functional interfaces
Using Java libraries from Clojure is often easier than using them from Java. You say this as a negative but the ability to tap that ecosystem easily when needed is a huge benefit. Having worked in many Clojure projects, needing to do so is not that common in my experience.
