That's it, I'm disabling "Find my mac". I guess it wouldn't work anyways if a thief is far away from my home or work wifi. So in essence, it's a remote wipe backdoor for when the device is in my possession, and useless if it's stolen.
FileVault2 should take care of the theft problem anyways.
Too bad you can't partially-enable Find my mac for the location service, while disabling the remote wipe and lock services.
