In the case of the right of privacy, what is wrong with your suggestion is that it is what we have today, and we end up where we are today. You must sacrifice your right of privacy to use Facebook, Twitter and others. And using Facebook, Twitter and others is not a choice for many people. It is forced on many (most?) by rules of employment (some schools require teachers to be on Facebook for example), economic reasons (must be on social media to be economically competitive), or just social (all my friends are there, so I need to be there too). Choosing to retain your right of privacy is a sacrifice, which is to say that maintaining your right of privacy has a cost. The EU has said that there should not be a cost to preserving what it sees as a right. Not everyone can afford to pay that cost.
