It’s not stealing, it’s unauthorised redistribution. They don’t lose anything from piracy, except for potential customers, which is a pretty intangiable concept. Don’t think it’s even remotely as bad as going into a tech store and taking all their DVR’s, or even literal piracy by chasing down another boat with guns and taking their cargo.
Even assuming ripping is legal (it usually isn’t ,though it should be), the effort required is significantly higher, the cost is significantly higher, and at least for TV shows, you usually suffer from huge delays as you wait for the season box set to be released. This is even assuming they bother to release a bluray in 4k with HDR.
Netflix and other services (assuming it even has the content you want) have fixed these issues, with the massive downside of no 4k, lower bitrate, and no ownership at the end of it.
Piracy, while more illegal, has the content you want, at 4k, usually a higher bitrate, with minimal effort, no cost, and no delays. Now that I’m employed, I don’t pirate music or games anymore, because the services offered are good enough that piracy isn’t worth the effort. But for movies & TV shows, the services offered are simply terrible.
