I have to say I can't really agree with that. Rights appear to be a construct of society.
That was the entire point of America to begin with. That no society would be created that would deprive someone of God given rights. As we forget that and shift the benefit of rights to the government we are losing them.
It might be because you are conflating our horde of created rights with the rights that come from the Creator. Freedom of Speech is a constructed right. Freedom of religion is a constructed right. The right to a trial by jury isn't a natural right. It's a created right.
Natural rights given by the Creator include the right to be let alone. To be able to rise or fall on their own merits. The right to order their own affairs. Drafts of the Declaration of Independence show that originally it said Life, Liberty and Property. It was later changed to pursuit of happiness. It should have stayed the way it was.
There is no such thing as a created right, fundamental rights are natural and innate: the right to free expression, the right to privacy, the right of self-determination, to marry, to vote, to have children no not. The Constitution and its case law create a framework balancing the interests of the state and individual.
The 14th Amendment, essentially a codification of the doctrine of inalienable rights, as expressed in the Declaration of Independence, is the engine which drives the mechanics of the Constitution ensuring a consistent application of individual liberties among all jurisdictions. That all persons will enjoy due process of the law, both procedural and substantive, and that all persons will enjoy equal protection of the law.
The Constitution both acknowledges the existence of inalienable rights and, just as importantly, ensures the process by which those rights may be expressed freely by the individual.
While there are inalienable rights, the right to free expression, privacy, to marry or have children aren't among those rights. Those are rights found in the Constitution. That doesn't mean they are inalienable. It means they are Constitutional.
