Natural rights people seem to believe that rights are physical possessions of individuals. You either have them or you don’t, and it does not have anything to do with what other people believe.
This is not completely bad as a frame of reverence in certain instances.
But it is necessary to understand that a right is a perception upon what is righteous in the context of an action. It is an abstraction, a rule. It manifests in the interpretations of intents and effects of a given situation.
So your right to property is only the understanding by other people that they should not seek to seize whatever you have, that action being considered wrong.
Your right to property depends upon such common understanding. Without it, it doesn’t even exist. You cannot say that a mob has violated your natural right to property if you’re the only person on the planet that thinks you own something.
You can argue that a society where people understand private property is more likely to achieve higher levels of affluence and an overall greater use of information and resources.
That doesn’t change the fact that rights rest upon the adherence and understanding of abstract rules that govern action, and are not physical things being carried around by “rights bearing entities”.
If you doubt it you can just do the empircal verification of moving to some place in Africa or Asia (or even in America) where they don’t like white people very much and where law enforcement is precarious and use your alleged natural right to free speech in an offensive way.
Rights derive from perceptions and understanding of those who are supposed to put those rights into use as a means of judging actions.
So it is inconsequential to try to define a right bearing entity.
What is relevant is to discuss what actions are understood as righteous, so them to judge the consequential actors by such.
We can spend the whole day discussing the metaphysical situation of a 16-month toddler, who can’t say “no” or “me” yet. Is she self-conscious, is she not? Is she a moral being?
But if we are to judge whether a pedophile who molested her should go to jail, such arguments are completely irrelevant.
We understand that the pedophile has violated standards of what is to be considered righteous action and we see him as liable to punishment for that.
The actual perception from the point of view of the toddler is something that will always remain subject to speculation, but in the end of the day it doesn’t matter.
What matters is that we live in a civilization that has agreed upon certain standards for righteous action, and that pedophilia is a violation of those.
Clearly a toddler of 16-month “has” not yet any “right” to decide things for herself, but that does not make us see her as some piece of meat that can be subjected to any sort of desecration.
We sanctify her human life, whether she does understand it already or not. We do that even though we se her as a growing individual which is not yet entitled to take many important decisions by herself. We understand that until she reaches that point, it is the duty of those who brought her to life by their own volition to take good care of her. And if they don’t, we shall make them pay for their inequities.
We also do not know how a fetus perceive the world or her own situation. Maybe it is really nothing, or almost nothing, at least until she forms the brain structures that we assume do the job as to perform such processes.
But then again it doesn’t matter what she perceives. What we are discussing is whether the decision of destroying her can be justified by her mother desires or not.
Our individual perception of such issue will them orient the formation of a justice principle that will be used to guide normative decisions regarding this category of problem.
If we are to be consistent in our moral feelings, and sactify human life that grows, whether or not it has reached any arbitrary decision taking threshold, we are to agree that such destruction is a violation and we should be against it. That negligence by her parents is an unjust and wicked behavior that we should not tolerate as part of civilized society.
