Sure, breaking the disc in half or cutting holes in it will destroy data, but that does not happen as a result of normal operation in functional systems.
Damage occurs if it just sits on your table for 5 years. Damage occurs even if you store it in a vacuum and without light and leave it there for a few years.
Damage occurs every time you put it in the DVD-reader/console.
Face it, DVDs and CDs get damaged in normal use, and experience loss of data even when not use, or never intentionally damaged.
That is the main reason they are so unsuitable for long-term data-storage for companies.
Even if you backup the data to them, then just leave them to optimal environmental conditions, data is still lost over a decade or two.
Everyone who's used a single CD or DVD over a period of few years knows that even in normal use, the surface gets damaged. It doesn't matter how little, or how infrequently. It happens. Therefore, over time, data is lost or corrupted. Therefore, your argument is invalidated, again.
Also, I notice you moving the goalposts,
yet again - at first it was that no data is lost over meaningful time periods. Then it was that no data is lost as long as they are handled properly.
