It is possible to install directly on the Mac, but yes, the Mac makes it annoyingly difficult to install Hugo directly.
For most users it’s trivial to install Hugo directly.
Apple, from my understanding, is not exactly welcoming to open source projects like Hugo and Go, and many others, and third party tools are required for a decent experience when using open source.
I don’t think that is going to change any time soon, and since the issue is really with imposed limitations by Apple and/or Homebrew, they are the ones you need to raise an issue with for a change that doesn’t put ridiculous amounts of work on individual developers or projects. YMMV.
