For collectors or even casual consumers, this secondary market has as much or more value than the primary market. My wife and son borrow an absurd amount of library books. I maintain a library of movies and games, most of which are second hand. And if I don’t like something, it goes back into the market for someone else to enjoy. There’s depreciation and an ultimate limit to how many times something can be lent, which only exists artificially in the digital world (libraries get so many “lends” of a digital license before they have to buy another). On the other hand, for end users, digital licenses are completely missing lending and selling and in some cases even backup and format shifting. Has the first sale doctrine ever been applied to these licenses in court?
