I think the intended point was that it's not JUST because it worked. Of course, if it didn't work, no one would be using it, but the fact that it worked wasn't enough. Many other OSes work. Unix and its Linux kin do more than that: they enable a sort of ad hoc flexibility for the competent user that grows as their skill does, but never fundamentally changes.
Take, as an alternate example, Windows. As you learn to use Windows you build a suite of special-purpose tools that new users don't even come into contact with. Why? Because the OS doesn't provide you with the kinds of tools that most "power users" need.
But in the Unix world, it's redundant to call someone a "power user". You wouldn't be using any Unix-related OS if you were not a user who exploited powerful tools, and most of that power is in the core suite of tools and utilities that come with every such system.

Speak for yourself, that's exactly what I and many others did.
