Is P3P designed to work only in an unregulated environment?
No, P3P is designed to work in a variety of regulatory environments. P3P is not meant to replace law, but rather to work with it. In an unregulated environment, P3P can help users see what personal information is being collected — this in itself would be an improvement over the current state of affairs in the U.S., for example. In a more regulated environment (such as that found in EU countries), P3P can help make users aware of data practices in a meaningful way.
