Summarized:
What's a right:
"Rights are legal, social, or ethical principles ... the fundamental normative rules ... according to some..."
Or, the specific type of right to our case, the "Claim Right":
"Person A has a claim that person B do something if and only if B has a duty to A to do that something."
...
If a person has a claim right against someone else, then that other person's liberty is limited. ... such as [walking on] other people's private property"
Where rights come from:
"Politics ... discussion about ... "rights" is ongoing...."
And the specific claim right of Copyrights within the United States:
"Copyright law ... part of federal law, and is authorized by the U.S. Constitution.
The Congress shall have Power ... by securing for limited Times ... Right to their respective Writings and Discoveries."
Or "it's this or that, maybe having to do with politics, and discussion is ongoing, but we think it comes from law or Constitution."
As I said, no understanding of what rights are or where they come from. Or rather, believe rights are things just generally agreed on based on the whims of contemporary culture, and which we commit to paper.
