1. Ripping a CD I just bought. Yes, I still buy CDs. So shoot me now.
2. Burning a bluray for backup. (I do backups on different media types just for insurance, and I like that blurays are write-once and incompetence and ransomware cannot fk with them.)
2. Failing that, just archive your existing discs and ditch the drive for good. It's the year 2020, and most (all?) software are distributed digitally, so you shouldn't need to get out your drive in the future.
I did archive all my CDs to HDD (gotta love 10Tb drives!! why buy anything less?), but I keep the CDs as backup in case (cough) the machine catches fire and burns up my hard drives (cough).
