CD lifespan loss isn’t from overplay, it’s from oxidation.
Periodic backups is a time consuming and costly process. Then there is the whole “verification” of the dupe. And the storage...
Scratched records will still play. Dirty records will still play.
90 years later even.
That was my point. If you want something you can play over and over for a couple of years with no loss of sound quality, CD is a good medium. If you want something that will last a much longer time and you aren't concerned about sound degredation then other mediums are better. It all depends what you are looking for. All mediums have their plusses and minuses.
