It's admittedly been harder than it used to be... I've been less inclined to buy CDs over just using streaming audio, since I pay for YouTube to go ad free, I use the music streaming kind of as a bonus.
On the Blu-ray front, I've tended to buy Blu-ray where available, but have bought DVD sets as well. There's also the high seas, so to speak for content that is not available for purchase/rent. I'd actually pay for a good AI upscaler software for DVD content if it worked under Linux (natively or via WINE). I left Windows outside of work a few years ago and not going back... I'm perfectly happy to pay for good, useful software even if I'm more inclined to look for open-source solutions first.
More so it would only need one drive. ODD is dead for at least 10 years and most people never need another internal drive at all.
