I literally burned and sold bootleg software to churches as one of my go to hustles as a kid, and have a blu ray burner handy.

Knowing how, and being willing to do it for piles of titles and make cases that are nice to display and browse in the real world alongside mass produced copies, takes a lot of effort and I have better things to do with my limited time.

As is tracking down very rare titles in blu ray quality. Often easier to just buy the most decent cased copies I can and rip for long term storage.
