> if we don't buy their books, they won't be able to produce the next one for people to pirate.
This is a false dichotomy. Book piracy and traditional book publishing co-exist. If book publishing wants to better compete with piracy, they can innovate like other industries have. As well, your implied prediction —- that if we don’t “stop all the downloading” [0] then books will disappear —- is decidedly ahistorical. Books have existed since long before publishing houses existed, and indeed it’s easier than ever to publish a book and get money for it.
