There is a difference, and not just a legal one. For DVDs and BluRays, the disc’s first purchase partly funds the people who worked on the disc’s contents. With pirating, nobody gets paid (unless the pirate(s) that is/are distributing the content accept donations).

Although that does make me wonder how different is buying a second-hand disc from pirating… other than the legal part, that is.

On one hand, woah!
On the other hand, I’m sorry :(

Did you prompt an LLM model for this text or did you come up with it on the spot? In case it’s the latter, you did a great job.
