I think you are missing the heart of the issue. Learning to use a lazy functional programming language remains relatively easy - we use to teach the basis in Ocaml in three hours when I was a student - and Git shows people can tolerate awful CLI tool UX. I think your point 3 is where most of people issues with Nix lie except I wouldn’t limit myself at a lack of practical enough documentation. Nix documentation pretty much just doesn’t exist period. If you want to use Nix, you will have to go through the packages or the implementation to understand what’s happening. That’s not very welcoming especially when you consider that’s the other Linux distributions which tried to do things differently in the past and could be a source of users for Nix OS, first of them Gentoo, have absolutely stellar documentation.
