In my mind (developer back then) I'd amateur-psychoanalyze all of that nonsense as some kind of inferiority complex meant to preserve the self image. Needless complexity can be a feature!
And now we are all developers!
Administrative work by nature leaves you a bit bored, if you do it right. So you sometimes pick something up just to play with.
I can't speak about every sysad experience, but in mine a lot of scripts tend to be in a "make once, remember for ten years" category, and even a bit of creative naming can help a long way.
Working with a larger codebase with "creative" code, on the other hand, is frustrating. And if you don't have to write code, you might as well go take a walk, "monitoring" isn't in your job description.
