I will pirate movies I already own the physical disks for. It's quicker and easier than finding the disk (and likely having to sit through the ads that are on it).

I started buying blu rays for the movies I really care to watch more than once. I can rip it to my Plex server and if I decide I don't want it I can go back to the local used movie shop and trade it in for some new discs.

That's the neat part. As they're a physical object.... They don't 'go away', their license doesn't expire.

You can just borrow them down at the library and rip them yourself, or buy them at a local discount store.
