Why do subjective values have no bearing on human interaction? Would you say that you've chosen your wife based on objective or subjective reasons?
And secondly, why would you say that an objective system cannot permit subjective values to result in coercive force between individuals? Your statement is itself one based on the subjective value that "there should not be coercive force between individuals".
The objective right is to associate with others. If you do not let people associate like they want they can not defend their rights.
That I have chosen my wife and that I have a contract (subjective, negotiation) with her does not make me or her more then other people concerning human rights.
You bring up a good point: People are free to associate, that means that if my wife would want to divorce me she should be able to do so, it is her human right, what I think of that will never change that right, it is not subjective!
People are free to associate, that means that people that have the might and force an 11 year old to marry someone they do not like are wrong. They have violated the right of the 11 year old to freely associate, no matter what might they have.
An other good point: Coercive force between individuals exists due to interaction and the that that interaction will give conflict. That is why you do need a way to handle that conflict. My conclusion is that using right for this is illogical from the definition of rights, they are subjective agreements, laws, merits etc...following out of a social negotiation. They in no way change rights, if you can change rights you can not defend them anymore, which is against the definition of rights, it is illogical.
Why can't we return to the natural state where survival of the fittest is king?
Survival of the fittest is a superb test case! I recommend all to use it to test their objectivity.
The fact that you can impose your value system with force, does not remove objective rights of the person (otherwise they would not be able to defend their rights), it only gives you the advantage in the subjective agreements, in the negotiation, the subjective part.
Stating otherwise would mean, if I can kill you (exercising might), you loose your rights. But then nobody could defend your rights anymore, so the processes against genocide would be nonsense, it was just "might is right". You can not loose your rights, it would be illogical.
It is a fact that people call rights things that are written in law, but that is illogical, since if you would change country, suddenly you could not defend your rights anymore, you would have to make new subjective agreements. We need to differentiate Objective Rights and Subjective agreements more clearly, so that people are not confused about it. Again only language.
Edit: The law of the Jungle (survival of the fittest) is subjective, it does not change the rights.
Why do human beings have rights and not, say, a baby cow? The attempt to apply subjective values to someone else is not objectively supported, but a baby cow cannot possibly understand that or live within the confines of it. The baby cow simply lives by the law of nature. This establishes a certain cognitive threshold for rights (let's ignore for a moment that that threshold is not well defined), and fetuses don't meet that threshold.
We are back to are rights innate or not. Logically they are innate (Please use logic on the contrary, it contradicts). You use value systems (if you understand rights you are of more value) above to state they are not innate.
In your definition the person killed does not meet the threshold, thus has no rights. But then nobody could defend your rights anymore, so the processes against genocide would be nonsense, the dead do not understand their rights so have none. You can not loose your rights, it would be illogical.
