Idk I like the idea of controlled digital lending. There was a really niche topic book (the seminal work on the expulsion of Zainichi Koreans from Japan to the DPRK post-WWII) that I had been trying to find for a while. It was out of print and fetching 100 plus dollars on the resale market and I couldn't find a library that had it. Luckily IA had a single copy that they are lending out to one user at a time via a DRM applet on their site. I have to check it out every hour in order to read it but I'm super grateful.
