Even as this is just a plan, for now, the worst scenerio that is coming out of this is exploring the issue of psychological resistance to the use of personal information thereby creating a negative mark on people who don't want their information shared with the government. Automatically if you choose not to share your information, you are labeled a subversive. This can't be good at all, and reminds me of the beginnings of a previous New Order.
The NWO is quite an interesting idea, but nothing more. It's easy to predict that things are going to happen as technology increases without attaching on a shadow group. Apart from the preaching, I couldn't see a plan like that succeeding considering that hackers would have a garage sale with everyone's information.
