There are many things that require tremendous practice and study that aren't worth your time as well.

You have to justify it somehow. And I just don't see the value prop in Nix yet. I would compare it as such: Nix is to Docker what Google+ was to Facebook. Maybe it's superior. But the benefits are so marginal that the costs of switching will prohibit most from giving it a shot. Most people want reproducible builds and easy configuration. If they are getting that from Docker, why switch?

At the distro level, average people are going to benefit by having reproducible builds done upstream. Debian does this, IIRC. As does F-Droid and a few others. If you trust Debian, then you implicitly trust the packages Debian installs.

NixOS doesn't even solve the real aspect of Linux that I find terrifying: security. Linux is a blob of overlapping and bewildering security mechanisms and tools. You have groups, permissions, SELinux, capabilities. The whole thing leaks like a sieve.
