Add to that the simplicity, physicality and aesthetics of the physical book. No DRM, no chance of remote deletion or modification, shareable, giveable, faster skims, and it can be just as beautiful as a etching, since with certain printing technologies that’s exactly what it is. For work ephemera, PDFs are probably the way to go. For pleasure, nothing comes close to a physical book...until you run out of space. Then it provides gainful employment to the building trades.
