The Rage and I discussed this recent posting on You Tube. The content creator is an expert on his online content and is also, IMHO, excellent at sales. However, there is no way I would spend almost $10, 000 on any book and/or have to (quote) 'finance' the purchase. Well-done, by the industrious presenter, as he sold other books to cover the cost, but I would never spend that much on any book (s) in the first place.
The Rage might have some of his own special books cleaned, pressed, slabbed and stored, for nowhere near even a thousand dollars...
My academic book purchasing was significant as a student. But overall, my academic and non-academic book collecting and reading has been significantly built through free online resources and downloads.
