PDFs constrain information by limiting the way it can be reproduced digitally. There is no such thing as "just" copy/pasting from a PDF - weird errors abound. The text has to be extensively reformatted or run through special software. A format is needed that encodes information visually and digitally. The digital layer doesn't have to be visible by default, just accessible when needed.
