However, it's not hard to compensate for this with digital books, through bookmarking options, copy-pasting specific parts and storing them elsewhere (with tiny notes on page number and book title) and other options.
I keep all of my own digital books DRM-stripped in my own device folders and back those up too. This to at least partly replicate the possession security that physical books give. I also absolutely never trust storing large collections of them on something as absurdly untrustworthy as, for example, "Kindle on Demand", which is on-demand right until your access demand arbitrarily gets ignored no matter how much money you spent on what were supposedly owned purchases.
But that's just me being stuck in my ways. So and I see the use of digital versions as well. Specially as a lot of my technical books now often coming with a digital copy! It's best of both worlds.
