You miss my point. It doesn't matter if it has never happened, that just means we have failed ourselves. What matters is defining the concept of rights, exploring what they mean and what they are. I'm not talking about if they exist in practice in any specific country, I'm talking about "what are rights?"

Rights are things reserved for individuals to hold unilaterally, sovereign over them, no democratic process or other consideration can take them away. That's the whole idea. That's at the core of the definition of the concept. Without that, the concept of rights doesn't exist.
