You're right, it's not the intended use of the security question - and that's exactly what I want. I feel like entering my pet's name doesn't add to my account security but rather lowers it. My password safe is stored at many different location so that it's extremely unlikely to loose them all at once. And to secure against amnesia or being-hit-by-a-truck, you should give the passphrase to a person you trust 100%.
