I completely agree with you about "identity theft" but I also keep the keys to my house private, although anybody who would burglarize me if I didn't would clearly be in the wrong and legally liable for my things.

Notwithstanding any legal or ethical judgement, being burglarized would cause me significant inconvenience and at the very least some sentimental losses, even if I were ultimately compensated years later with interest. Therefore, I keep my keys private to protect myself.
