There are negative rights and positive rights. The former is freedom from other humans doing things to and the second is requires other humans to do something for you.

I believe that only negative rights are and can be inherent.

You can build social contracts that help people get services and materials on top of this, because people care about each other.

There is no such thing as inherent right, every right must be earned or fight for.

Is/ought.

Rights are oughts, not ises, IMO. (Oughts which I believe in, but still oughts).

I agree, but this is a matter of semantics. There is nothing in the physical universe that supports morality.

Rights are components of a moral framework, inherently philosophical - unless you believe in a god. When someone says something IS a right, they are really saying "This is a fundamental assumption in the moral framework I believe to describe a just world"
