It's a pretty typical symptom I've seen a lot of hardcore FP developers exhibit: they forget how much time it took them to reach their level of mastery. It's like spending ten years learning to speak Russian and then criticizing anyone who says that learning Russian is difficult. Puzzling out scalaz code is difficult and requires an enormous investment in hours and practice, investment that a lot of people prefer to put into different learnings.

Mainstream developers forget just how much time they invest in learning the latest fad frameworks with new ad-hoc concepts and terminology. I guess "Hardcore FP developers" are fed up with this state of affairs and are looking towards mathematics to provide guidance and common patterns/names. At least any knowledge of mathematics will not become outdated!

Yea, puzzling out some scalaz code takes investment. On the other hand, the library is used for web apps, network servers, database based applications, streaming libraries etc. It's incredibly multipurpose, more so than even Spring or Guava or LINQ, and these are things that developers regularly have to invest serious time in. The argument is just that FP libraries (like Scalaz) have a bigger payoff in the investment. At Verizon Labs were have 20+ microservices that I have touched/looked at. Some use Akka, some use Play, some use Jetty, some use Http4s but everyone makes use of Scalaz somehow.

It depends on the people, not everybody has the inclination to dive so deep into hard core FP and they will be more productive using a different approach. Don't make the mistake of thinking you've found the only software silver bullet that exists and that people who don't use it "don't get it", which is another attitude I've seen a lot of hardcore FP advocates embrace.
