Nobody cares about what pmoriarty1 thinks of a word when the legal and political worlds have well-established meanings for those words; meanings that indicate the parent poster is correct in stating IP rights are not "natural" in genesis.
There is a recent movement trying to redefine them as such, led by moneyed interests that would obviously stand to profit from such arguments; but legal history is very clear: IP was never conceived on the grounds of being "natural" or "innate" in any way, but as a device to sustain certain economic sectors. IP is no more natural than subsidies for carmakers are natural.
