> DVD deteriorates to the point of becoming unreadable

If I am the reason for damaging my purchase then I am fine with that characteristic of the purchase.

Same happens with books, you buy the copy and if you don't take care of it, soon it will become unreadable.

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
