It's significantly cheaper! A physical book can be loaned endlessly, as long as the binding holds up, and even if it gets damaged, it can be repaired. The contracts for ebooks at libraries often limit it to X number of circulations before the library has to pay again (this is how Overdrive/Libby works), or they have to pay per circulation (Hoopla). It's ludicrous.

Yeah that's a shitty model. We desperately need digital ownership rights.
