Porn is probably the most pirated visual work that I'm aware of and I've noticed that one of the responses by the people who make it is to move their business model away from restricting access indefinitely to producing custom/bespoke pieces at a relatively high one-off price to compensate for cases where it immediately gets proliferated without further gain for themselves. If someone pays them to make the clip and then shares it with others it's OK because the producer has been rewarded in full at the point of sale. This is roughly equivalent to a piece of art being bought or commissioned and paid for in full by a museum or gallery, who put it on public display and make digital copies available for people to make their own prints from.

From an artist's POV this is much simpler and more economical than trying to gather royalties on an ongoing basis and enforce copyright to create false scarcity.

In my solarpunk future though, I will be an artist whose basic needs are met by machines and nature and who receives a universal basic income which I can give away to other artisans as a way to say thanks and to encourage them.
