To be clear, property rights don't come from laws; they are natural rights. "Property" as a concept stems from the fact that when Caveman Oog gets himself a neat tool-shaped rock and is holding it in his hand, nobody else can use it because he's the one who has it, and the only way they could use it is for him to not have it anymore. He controls it and its use is exclusive to him. The rock is his property. The law doesn't create that concept; it only codifies it so that the rock can remain Oog's when he sets it down, instead of him having to guard it all day.

"Corporate" "property" "rights" are a whole different thing:

1. Contrary to the Dred Scott-level bullshit the SCOTUS excreted in Citizens United, corporations are not people and don't even have an inherent right to exist, let alone any other rights. A person (i.e. a sole proprietor) has rights. People associating with each other (i.e. a full-liability general partnership) have rights. A group granted the privileges of limited liability and taxation as a separate entity via incorporation exists at the pleasure of the State, and the State has every right to impose conditions on that existence in exchange for granting the privilege.

2. Copyright is not "property." A copyrighted work is an expression of an idea, and ideas are as near to opposite of property as it is possible to be. Not only does an idea stand in stark contrast to Oog's rock in that it can be freely shared to the other cavemen without Oog losing possession of it, the value of it comes from the act of sharing. A creative work that never leaves the creator's head is worthless, while a work shared with the whole world is incredibly valuable. (Don't take my word for it, though: Thomas Jefferson -- the guy who wrote or helped write the Copyright Clause, BTW -- made a similar point, more eloquently explained.)

3. Copyright isn't a "right" either. It, like incorporation, is a privilege granted by the State (or more specifically, Congress, but Federalism is beside the point). It does not exist because the creator of a work is somehow entitled to it, or even because the People wish to reward creators for their work. Copyright exists for the sole and express purpose "to promote the progress of science and the useful arts" -- in other words, to enrich the Public Domain. The mechanism of copyright, granting a temporary monopoly in order to encourage the creation of more works than would otherwise exist, is nothing more than a means to an end. The goal of copyright is for it to expire!

Anyway, point is, I'm kinda already making that distinction between basic human dignity (natural rights) and artificial laws (copyright). The situation we find ourselves in today, where actual property rights of actual people are being subordinated to ~~Intellectual~~ Imaginary Property "rights" of imaginary "people" is some pants-on-head stupid, ass-backwards, Bizarro-world bullshit!
