Earlier quoted context omitted.
What you’re proposing would require a literal quantum shift in DRM, where it’s only possible to use a copy of something if that thing hasn’t been itself copied somewhere else. That world would ironically unite the desires of publishers, creators, and actual archivists, leaving only the pirates out in the cold. Whoever figures out how to do that is going to make a fortune.
No you wouldn't. It's not about DRM, it's about the contractual agreements between libraries and publishers. They already track the number of times it's borrowed and for how long. OP is suggesting that it should be dealt with the same as a hard copy, i.e. only one person can borrow it at a time.
Secondly, you should reread their post, it’s much broader than your interpretation. They were envisioning a world where the device and copying restrictions we have today don’t exist.
