Because then they're too dependent of the content, which may change, 
because you can't use some values (like 0, or very low values) without 
screwing up the object scale, because you cannot use negative values, 
and because you can't set a width/height if there's no readily visible 
assets inside of it. Those are conditions in which changing the *scale* 
instead works as expected.

Of course using scale means you have to know what's the scale instead, 
so mathematically it can be more difficult animating to it, but it's a 
'more correct' way of doing things most of the time. Not *every* time - 
if you want to scale a single, static image, it makes sense to use width 
and height - but *most* of the time.
