If anything, your rebuttal is in bad faith. Programming languages are not that dependent on the number of users as human languages are - which are more akin to protocols that both speaker and receiver has to know.

What reason is there to prevent someone who learnt this language to utilize it to “communicate with their computer” and share it with the rest of us? And I say that as someone who do like Clojure for example very much.

My opinion/answer is that while lisps have plenty of properties that make them great and that one gets used to all the parentheses, we as humans in the end are simply find it more alien then other languages, too uniform of a syntax hinders human parseability. (That’s why I think that clojure made a very great and pragmatic choice by introducing some other primitive data structures).
