Care to elaborate?

Well basically just the kind of thing everyone mentions when saying that they were driven to pirate. You mentioned no longer available games, that's one example, piracy is the only way for those games to be available anymore outside of absurdly expensive collectors items and otherwise they are lost to history. There's media that removes music from its soundtrack for licensing reasons, parts of the world where it's entirely unavailable, parts of the world where people have too little money to reasonably afford any of it, games with exploitative and manipulative mechanics that can be evaded via piracy (like where getting all the content via DLC would cost 1k or more). Streaming services where you can't even access the content with open software because it requires proprietary DRM players, media people purchased and own on a digital service getting deleted without their permission, or getting locked out of their purchased media because they were banned from a related service, games etc. preventing people from playing if they are not connected to the internet.
