A cropped section of a wide-angle shot is EXACTLY the same compositionally as using a telephoto lens. (But of course it will be lower quality.)
Not true. At the same settings (shutter speed/aperture/ISO), if you have a crop of a wide angle shot you'll have a lot more depth of field than if you were to zoom in on that cropped piece of the scene with a zoom lens to fill the frame. This is one of the reasons people use a longer lens for portraits since longer lenses do a better job of throwing the background out of focus.
