What actually surprises me is that the author bought 11 paper books from Amazon about NFTs. You really need 11 books to understand or write about a single concept? It is a highly controversial ongoing topic. Those 11 books most likely become obsolete exactly on the day after they were written.

Good catch on the one fake book! But I am surprised it was only one. Maybe the author started from that one and will write about the others later.

The author bought 11 paper books because they wanted to make money posting a meta-review of the literature analyzing the arguments from all of them together. While they probably understood the points after a single book, they would have lacked the complete coverage (and the marketing hook).

I would expect someone writing that to have read the 11 most popular books.

The author didn't want to "understand a single concept" this way, but rather, as they say themselves, "get familiar with the best-articulated arguments put forward by the proponents of this tech".
