I feel the exact same way (s)he does about node.js and I 100% would never want to write Clojure. So to your point, yes. Using the language I know well enough to make money with is awesome. Other languages don't entice me because I can already do everything I need to well with what I currently have.

This is a provincial take. That is, “do everything I need to” is strongly limited by what a person currently knows. If you don’t have at least moderate amounts of experience with alternative ways of thinking, it’s impossible to know what you are missing. There are many things which are needlessly complex, slow, brittle, unproductive, ... in any particular programming environment, and javascript is one of the more limiting choices IMO.
Ideally, students would be exposed to a broad range of approaches and tools in school to build a strong foundation, but in practice this often doesn’t happen, and the folks I know who reliably build the best systems are the ones who spend a decent fraction of their time learning new tools and ideas throughout their careers, many entirely self taught.
Probably because you don't need to do things that Node isn't well suited for. If you did, then other languages which did those things well would become useful to you.
You can make any language do anything if you have days/months/years of free time, but NodeJS isn't suitable for systems programming. Imagine trying to write a tcp load balancer or interface with Linux specific kernel APIs from Javascript. It's not a great choice for a CLI tool since there's inherent startup time for JITed VM based language. It doesn't scale well for CPU bound thread pool applications like image processing, etc.
So there are lots of places where it doesn't make any sense at all or it's just a very, very poor choice for a particular task.
Some more would be statistical (R, Matlab, SPSS), gaming outside the web (C, C++, Java), scientific computing (Python, Fortran, Julia), supercomputing simulations (Fortran, C++, C), embedded devices (C, C++, Rust), server farms (C++, Go, Java), financial (Java, Cobol, J/K), to name three PLs in each category that come to mind.
There is a big world of computing outside of apps and websites.
People use Clojure for all of those. From the rationale (https://clojure.org/about/rationale), Clojure "endeavors to be a general-purpose language suitable in those areas where Java is suitable".
