That isn&#x27;t particularly relevant. Value to purchasers is not constant. With a higher price, you generally get fewer purchasers, and with a lower price, more. I could argue that the maximum net societal value for any already-written book is generated by having a price of zero. The question of price then becomes one of incentive: what price generates sufficient profit to motivate the creation of cultural products? A price that generates billions for the author is probably too high.
