There are a few optical storage mediums designed for long term archival storage. Like M-Disc or (as mentioned in the article) pioneers DM for Archive, both of which are still commercially available.
And provided they’re stored properly, even more general consumer oriented optical media can easily last a few decades. Granted the environmental aspect of “proper storage” (<50% relative humidity, constant temp <80F and >50F) can be difficult to achieve at home in a lot of regions, but generally banks and credit unions have an option to get a safety deposit box which is generally in an environmentally controlled room. Other than that just store your media in an opaque single disc case.
So it is one option less to store data long term and inaccessible to covert internet surviallance, but only the plebs are restricted.
using optical media for long term storage is quite a bad idea. Especially R/RW media. They tend to (although not always) degrade quite quickly

Even the bank safes are useless in hot and humid cities if you want to preserve anything for say 10 to 20 years.
Optical media is not long term. Hurry up to backup your DVD videos and games, before you can’t anymore.
Recordable media isn’t. Factory pressed media if stored correctly should outlast the person who bought it.
Should. Real is about 20 years even for big libraries. I’ve seen bad DVD (plastic gone dull) in the library of ETHZ.
