Some people want the thing done more than they want to do the thing. That gets to extremes of exploitative parasitic behavior, but it's true at much less obnoxious scales: ever used a programming language's standard library instead of inventing your own _whatever_? Probably a yes.

That can extend to arbitrary absurdity. You are probably not growing your own food, mining your own ore, forging your own tools, etc etc etc.

It's all just a matter of where you rely on external tools/abstractions to do parts of the work you don't want to do yourself.
