Clojure would not gain widespread adoption even if all your points were fixed. The sad reality is that 99% of developers out there are instantly turned off by the parens and absence of while loops.
I'm seeing Clojure related posts on top of HN almost every week. And I'm watching people trying Clojure, coming with all sorts of different backgrounds. I have worked with people who came to Clojure from C++, Ruby, Python, C#, Haskell, Go, Scala, OCaml, JavaScript, CL; people with no programming experience at all.
Of course, that all is incomparable with the craze that something like Typescript receives. And I used to feel anxious, worried that this would be the last ever job where I happily used Clojure. But after my third job where Clojure was the primary language, I stopped sweating about that.
I think Clojure, at this point, has stabilized in the industry and slowly and steadily would continue to attract people. The only thing that can genuinely kill Clojure - is a better version of its fork.
But as you say, it's popular "for a Lisp dialect" and I don't expect it to reach past that. I would love to be proven wrong.
That being said, your post made me realize that instead of lamenting the nicheness of Lisps, I should be encouraging other people to give Clojure a shot. And not only to help Clojure be more successful, but also to bring a little bit of joy to their daily life like Clojure often does. (It sounds trite but it's true.)
