Enforcement of the right to privacy works (more or less) for offline privacy invasions. I believe the problem might rather be, that there's a lack of clearness and awareness when it comes to how privacy does apply to online matters. Even technically knowledgeable people are often caught completely off guard by how much you can actually glean and deduce from very limited data. Most people wouldn't believe how revealing some seemingly innocuous data can be, when you collect enough of it.
