I think that like everything else this is about balance. Dependencies appear to be zero cost whereas writing something small (even 400 lines of code) costs time and appears to have a larger cost than pulling in that dependency (and it's dependencies, and so on). That cost is there, it is just much better hidden and so people fall for it. If you knew the real cost you probably would not pull in that dependency.
