Interestingly, it seemed at the time that books were just about the least exciting things being sold on the Internet, and the shipping costs looked fatal to the business. You could buy just about anything, and everybody was going out of business trying to compete on big ticket items like electronics and movies and games and beanie babies. Not much competition on books online (anybody remember the “Duwamish book store demo” from Microsoft?). It seems to me that he looked way out and thought about how things would be done 20 years hence, regardless of what made sense at the time, and chose to start on the piece of that future with the weakest competition.
