The problem is in how the PDF standard works. Each block of text, encrypted or not, is checksummed. Likewise, each page is its own object. (I'm speaking a bit loosely as it's been a few years since I've written PDF code). Between the checksumming of each object on each page and some of the other features, it's actually quite difficult to remove or change a single object without recomputing changes across the whole document.
