"each page individual customers read of your book, the first time they read it"
So, you write a technical manual. 60% of it deals with corner cases that few people ever need to read but if anyone needs to read up on one of those they really, really need it. But about 10% is valuable reference stuff that readers keep going back to. So most readers read 30% of the book once and pay for it once, they read 10% a lot but still only pay for it once and have the reassurance that the other 60% is there and that has value for them but they pay for little or any of it. Somehow that doesn't seem like a fair basis for payment, at least not for a reference work.
