In the meantime, within that year, 1000 more authors create books like this. By the end of the year you have 1000 resolved cases and 1000 new cases. This can continue forever, with the result that 1000 books are always available for sale.
You might say, the authors could be penalized so as to scare new authors away from this. However, the probability that a court will impose sufficiently large fines on the authors is close to zero. Even if they did, many authors could be (or claim to be) based abroad and therefore (in practice) cannot be fined by the US court system.
Do you have any solution to this problem that doesn't involve Amazon acting without a court decision?
If someone sees a problem with my example, please let me know. I am not trying to impose my views on anyone, I'm genuinely trying to understand the mechanisms at play, the concerns, and the possible solutions.
