> To build it outside of clojure ecosystem, you would need to first build all the pieces of the clojure ecosystem

That's simply untrue, and even the author's conclusions contradict your point. You can already do all of these things with just javascript. And if you're arguing that javascript has rebuilt the entire clojure ecosystem, then what is the non-aesthetic case for clojure?

I like clojure a lot and I've made a few toy projects with it, but I see its primary value as helping me write better code in all languages I use.
