/me not subject to USA law.
I've already said that I think "rights" are a fiction; so to me, inalienable rights are an inalienable fiction. Just because they've been written down doesn't make them real.
What are these rights? (I'm not asking for their enumeration; I want to know where they come from, what they're made of, if you like). I did philosophy at University (a long time ago), including a module on political philosophy. I don't know of any basis for the notion of a "right", other than privileges freely granted by others.
So, for example, I have a right to a state pension; I've paid for it all my working life, and I'm over 65. But the government can infringe that supposed right simply by passing a budget that abolishes it. It's a privilege, not a right.
The US constitution claims to protect these "rights" from infringement by legislators, enforced by the Supreme Court. But I have to say, the Supreme Court nowadays looks more like just another legislative body than a superior appeals court.
