Yeah, they do. Unless you're buying expensive archive quality discs, they only last 20-50 years. Tops on optical is about 300 years, IN an archive, not being touched or used. I'd work on that aspect. Look into long term storage and preservation techniques. You know, if that's the goal.

You're not making a fucking time capsule. 20 years of something being reposted to the internet after it's been banned is more than enough to preserve it.

Yeah, but what I'm talking about is not the fact that the disk dies at = 20 years old. Things like poor ink quality, delamination, and other poor production techniques make the shelf life vary wildly. So you're trying your best to preserve something, but doing it on a highly unpredictable medium. He seemed to have archival purposes and I wondered if he had taken the time to research the different ways to attempt permanent archiving.

You could always rotate the optical stock if you can't do CD-A. It's the best option available within reason. Printing stuff out will work. Nothing is forever but there are ways to try to preserve it.

I wish more research would go into holographic storage inside crystalline substrates. Those would be more Rock solid and would remove the chances of direct interaction with the interior data points. If the surface is scratched, hopefully not on a sufficiently hard material i.e. diamond or graphene, you could buff it up and ideally the data would be preserved.
