I understand the sentiment. When I buy a book now I first decide if I will ever want to loan it to someone, and if yes, then I buy a physical book. For the books I write I now only sell eBooks but under a Creative Commons Share and Share Alike license and I encourage people to share with friends. Writing books is a lot of work and I want them to be widely available. Then, you may ask, why not just put PDFs in the public domain? The answer is that I do enjoy getting some revenue from writing, so it is a compromise.
