I would expect scientists to lean more toward a system based on a notion of natural rights, rather tha on legal technicalities, but I admit a tendency to project. That's curious, I would expect completely the opposite. Are "natural rights" empirically observed? How would you attempt to test or falsify a natural right? Does the concept of a natural right provide any predictive power? How would the existence or non-existence of a natural right change the observed nature of the universe? The whole concept of "natural rights" sounds suspiciously like moral realism, which is about as anti-scientific as you can get.
