Au contraire. I said "in cases where the content is made especially  
for the output device", as opposed to general Web content. So the  
author would know the monitor dpi and UA default zoom choice. Keep in  
mind that CSS is not just for Web pages.

And in the case of user style sheets, these would be used where the  
user did know that the page scaling was always wrong when viewing Web  
pages in his browser.
