Hello Salman,
The problem with "normal users" cooking up new styles is the lack of artistic abilities in some people (like me).
But you will never gain artistic abilities by simple copy/paste.
One can, obviously go thru the manual cover the cover, but if one does not have creative thinking, then creating professional looking styles would be hard. That is why, users like me really do not care if our documents look like everybody else's (just as long as they look professional).
The ability to know how to program/use a text editor/use photoshop can only help you with the technical difficulties in making a professional cover and style. Not more.
And of course, once we learn the tool, then making small changes here and there to make it look slightly different is no big deal.
Each LaTeX document looks slighlty different. But overall they are extremely easy to classify as a LaTeX document. And why? The distances and parameters are all given so it looks "right" and there is no reason to change them.
