I mean, I'd really have to disagree, but that's fine.

The effort involved with deconstructing a book, batching it through a document scanner, and compiling it with OCR in a EBOOK-compatible format is not trivial. Most consumer-quality OCR software isn't even that great at recognizing words, new lines, symbols, and hyphenated and line-broken words, let alone recognizing chapters, indexes, footnotes, ect. It's just not something that would be worthwhile for what it produces in the end, and there are millions more print titles than there are movie and show titles.

On the other hand, with A/V there's almost always a way to pass playback through a virtual media capture device. Worst-case you have to wait the real run-time in order to capture it, but at the end you at least have a near-original quality file.

If tomorrow all EBOOKs got locked down without a means to strip DRM, I don't think anyone outside of historical archivists would start spending their time manually cataloguing copyrighted hard copy books to distribute freely. Best-case, only the highest-demanded books would justify that amount of effort, and certainly not enough books to sustain a digital library worth frequenting.
