> Aren't brick-and-mortar bookshops, generally speaking, as viable as Apatosaurus today?

Not really. Plenty of people still read, and they still read hard copies of books. I don't think you will get argument that business isn't as good as it used to be, but that's a long way away from not being viable at all.

> Also — secondhand books are generally outdated, undesirable, and/or damaged — do collectors still find diamonds in the rough?

You haven't spent much time around secondhand book stores, I'm guessing? Yes, there are absolutely diamonds out there. And even outside of that, there are lots of perfectly good used books. Books don't go bad over time, so unless they're damaged (which isn't most of them) they are still perfectly saleable.
