In my humble opinion, a zoom lens is not the equivalent of moving one's feet. The distance from the subject to the film plane (sensor) is completely different from the choice of focal length needed to crop the image. And both of those impact the depth of field at a particular aperture. The biggest disservice that zoom lenses have done to the photographer is make him think less about moving his feet (location).
This is not to say that cropping after the fact might not improve things. Cropping is not a sin. Nor is using zoom lenses for that matter. But I dislike it when people (subconsciously) think that they can do the same thing by zooming as they can by moving closer to the object. They are two different things.
