I am serious. I see no difference.

Risk = Impact X Probability. I submit to you that there is a much higher probability that a corporate level mistake is made than that a hacker successfully breaks into a secure database. You could argue that the impact of the hacker is more significant, although that assumes that the accidentally-lost data doesn't end up in criminal hands.

Look, I'm not saying that you should put your SSN on your business cards, obviously individual responsibility is important. I'm just saying that even if you are responsible you aren't necessarily making yourself significantly more safe.
