DVDs degrade naturally. Good care will extend the lifespan but not indefinitely.

Other things as well degrade naturally, some faster, some slower, some depending on the use.

I am fine with that characteristic of the purchase, I am not fine when my purchase can be taken away from me abruptly by the decision of random Joe

I’m still playing CDs from 1985 without any issue. And they often sound way nicer than overcompressed remasters I can find on Spotify. Would it be different with DVDs for a reason I ignore ?

They may be more susceptible due to the finer grooves alone, I guess? Although so far I've also never had any DVD or Blu-ray go bad.

Recordable discs are another matter, though. Much more sensitive because the pits are "burned" instead of "pressed" (not sure about the correct terminology). And some of those materials were so bad that back in the day, I often had blank discs that went bad before I even had a chance to burn them. Nowadays I'm using M-Discs and hope they'll hold up their promise. They should outlive me, anyway.
