furthermore, just because people want to arbitrarily call something a natural right doesn't mean it actually is a natural right. For example, people have this mythical idea that a natural right to life exists. Nothing could be further from the truth. The one thing we know for certain is that nature has made it very clear that we do not have a right to life. If we did, there'd be no such thing as death. We'd all live forever.
But we don't live forever. Nature doesn't allow it.
It can't be a natural right if the only thing that we can guarantee about it is that it will definitely be lost at some time.
