Of course there's limited commercial value in holding intellectual property without legal protection, because there's limited commercial value in holding any type of property without legal protection. But that's completely beside the point of the natural law argument.
For what it's worth, I don't actually agree with this argument; I was just pointing out that it's possible to use natural law to argue in favor of intellectual property rights.
