Missing elbow

What is it about the marketing mind that believes false or forced perspective, the erasing or addition of body parts is so important in advertising that it is such a common practice? I wonder, is it contempt for the average consumer that leads to such errors a child with a PC would not make. Or is it that ads with such "errors" are considered a stylized form of art and are legitimate as they are?

Don't know if this qualifies as a Photoshop Disaster but the erasing of an apparently aesthetically displeasing elbow seems a bit of a hasty decision. I, for one, think Ashley Judd's elbows are cute and they should have been left in the photo, if in fact the lower half of that body is actually hers.
