Actually, copy/paste makes a lot of sense. Having to frequently copy or move files from one place to another, I got used to ctrl-c or -x a file, then go to a different directory, and ctrl-v. The appeal, I think, is that I don't have to use the mouse (which employs a time-costly drag operation). Dragging files into directories is also cognitively expensive - e.g. you have to make certain that you are dragging exactly into the right folder which can be about 15 pixels high, depending on what view you're using. It requires hand-eye coordination which becomes unnecessary with simple copy/paste operations. BUT, for beginner users, I agree: users have a hard time grasping the concept of a copy/paste buffer anyway, and with files it gets abstracted one more level. For more advanced users, they use keyboard shortcuts, so the buttons don't really need to be there.
