I’m not sure why you would lug around an entire bookshelf when you could just throw all of the books on an e-reader and carry around an entire library in your pocket. Maybe that’s the “conceptual” point. Fighting the power! Or something like that.
The transportable bookshelf is made using crates originally used to haul fruit. I love, love, love books, but I think in this case I’d prefer the fruit. Plus, I didn’t have any breakfast this morning.
