Then it's worth being careful with the things you purchase.

Seriously, that's like saying "buy the extended warranty when you buy a 
phone/pda/whatever because you wouldn't want it to get damaged" - last 
time I was offered that, I told the seller that unlike most people, I 
treat my purchases with care and make sure they're not going to get 
dropped.

I have CDs and DVDs that I purchased years ago that I have no problems 
with.
