It also allows for monopoles. Fundamentally, copyright is the right to have a monopoly on the idea, which would be fine if it wasn't abused. Like in streaming services. Anyone who didn't feel like watching something with subtitles and tried to filter for only dubbed shows, or speak multiple languages, knows that the service is shit on all of them and the competition is entirely based on exclusive rights on media. That is obviously not how copyright is intended. There is no reason why e.g. netflix could buy the right for xyz for abc money and Disney plus shouldn't be able to buy the same rights for the same show for the same price. Not if you want to claim that the point of copyright is to allow the creator to profit from their work.

Have fun

The printing press came into use in Europe in the 1400s and 1500s, and made it much cheaper to produce books. As there was initially no copyright law, anyone could buy or rent a press and print any text. Popular new works were immediately re-set and re-published by competitors, so printers needed a constant stream of new material. Fees paid to authors for new works were high, and significantly supplemented the incomes of many academics.
