Security is about placing the appropriate level of a control in place.
I agree that this type of social rights management would probably fail because some companies would try to include personal information in the file (like credit card numbers). When they did that then people would spend the effort to remove the information because there is a chance it will get lost or stolen.

Full name would be enough -- credit card numbers change over time, and that would present a security risk. The data could be hidden and be randomly distributed. Sure there always will be ways to remove such items. There are good reasons for removing DRM --- there are no good reasons for removing a watermark. Watermarking would give honest users every right they could reasonably ask for.
