I feel like it's a philosophical question.

I like freedom and diversity. I don't want Linux to be like Windows or macOS with one window manager, one init system, etc. I like that people (and I) can experiment.

Is it less efficient than paying for Windows and macOS? Probably. Is it less polished? Certainly. But that's exactly what I want. If I wanted Windows or macOS, I would use Windows or macOS.
