The immorality of copyright infringement is not contingent on whether the industry can survive in spite of it any more than the immorality of traditional theft

The immorality of copyright infringement is not contingent on whether the industry can survive in spite of it any more than the immorality of traditional theft is contingent on whether the victim can afford to suffer the loss. The fact I have an Ikea-style ball pit in my basement filled with money doesn't entitle you to come in and grab a handful. Even if you're only just borrowing it, even if you do actually give it back later, and even if I don't even notice you took it, it's wrong.
