Enforcing that right is often expensive, far more costly than money you would receive, and the risks for people on the infringement side very often have near-zero risk, and low cost in the rare case they are caught.

I came here to bring this up specifically. Tony Northrup had a video about someone across the globe stealing his content and brought up how extremely costly it was. He was mad, could afford it, and was gonna fight cause they did it to him twice, from what I recall, but I do remember a point in the video where he was talking about how it became a matter of principle over money at a certain point because of the cost in money and time sink. I can’t remember if he said $50,000 or $500,000, I lean towards the 50, but either way, that’s a lot of money to fight for one picture.
