I have a feeling that this is going to turn out to be one of our more epic blog discussions.

The NAP to my mind doesn't provide for any sort of "common defense". If steemit is compelled by law to give away your information then they must do it. If they do not, then they run the risk of losing their own individual freedoms.

It's not a violation of NAP to "give up" someone else. It's a violation to do anything directly to harm them.
