I totally agree with this as long as we're talking about documents - mostly consisting of text, to be read top to bottom (or some other direction, depending on locale). It gets hairy if we're talking about graphical applications where text only plays a minor role, and most of the visual elements have size constraints. It's very hard to have all those visual elements and their interactions scale smoothly to any dimensions or color schemes the user may choose. So, for those applications the designer usually chooses a few predefined UI styles, and tries to prevent the user from messing with those, as the result of that messing would only look bad and glitchy.
