For many of us it's not about some cost/benefit analysis, but passion and curiosity.
Except in the sense that everything is a benefit (including shooting heroin, where the benefit is the high, and so on) where the term becomes meaningless. But even so, it still wouldn't be "objectively perceived". More like "subjectively pursued and felt".
Sure, you're welcome to just stop examining thoughts at the surface level and not dig deeper. Other people here seem content with that. I'm not.
