OK, I'll buy this. At first I couldn't think of a real use-case that matched your description, but then I realized one that might be close - Say I want to copy some pictures in a directory that relate to a craigslist posting over into another directory. I've done that. And since I only ever use those photos once, I prefer not to import them into something like iPhoto or the like. So that's a case for having a GUI file manager, but (back to the original point), I'm not sure it's a case for cut n' paste.
