First of all, what's with the OR?
Who comes first? The People or the States?
So, as long as a right isn't enumerated a State is authorized to restrict it?
Basically. Look at the prohibition of alcohol for example. When the federal government was acting with in its proper boundaries it couldn't restrict the sale of alcohol, so the temperance movement needed the 18th amendment. But
states could prohibit alcohol. Even today you have "dry counties" and "wet counties". Drinking alcohol isn't an enumerated right. On the flip side a state law banning any newspaper that criticized the governor would be struck down.
So by this reasoning, any state can restrict property, and then authorize the federal government to act on their behalf for whatever they've enabled.
I'm not following you. First what would even be the point of that? The states collectively have more enforcement officers than the federal government. Secondly, states restrict property all of the time. Zoning laws for instance. Can you think of any example where or local government passed an zoning law and then asked the feds to enforce it? Third I've never heard of a "state to federal delegation doctrine" on anything. But even if that did happen, why would it even matter? In the grand scheme of things if your property right has been restricted anyway, does it matter if it's a local sheriff or a federal agent that enforces the restriction? It matters who passes it because you have a better chance fighting city hall then you do the federal government.
Why not?
Why does or should a person have any rights that aren't written on paper?
I'm leaning towards it doesn't exist. Can you tell me why I'm wrong?
Ummm....I'm not the one arguing for an unenumerated right. That said there are common law rights. Ok, they're written in court decisions but still.
The Supreme Court is authorized to interpret the Constitution, which is de facto law and rights creation, is it not?
The Supreme Court CAN, in theory, and effect say "The first amendment really means a person can murder as long as it's part of his religion" right?
The Supreme Court authorized itself to interpret the constitution. Kind of circular reasoning.

The current court view on religion is that you have and unfettered right of your religious
belief but not an unfettered right of
action based on your belief. So you can't murder someone just because your religion says so. You can
believe someone deserves death and even tell others of your belief as long as you aren't directing them to carry out the murder. Its the same reasoning by which the court should overturn that state school's decision to try to force that Christian counseling student to change her views about homosexuality. That is if the court follows its own precedence.
But back to the subject at hand, if we accept that whatever the court has already said is constitutional really is, then the whole discussion about this racist couple is moot. The court has already made it clear that the federal government can do all sorts of things in the name of "interstate commerce" even when there is no real interstate transaction involved. But the court has revisited the commerce clause somewhat in recent years and started to reverse itself. It came close to totally undoing the broad definition of the commerce clause in Gonzales v. Raich, but Scalia apparently couldn't bear the death of the federal drug war.
Side note, the only reason the court gave a broad definition of the commerce clause in the first place is because FDR bullied it my threatening to increase the number of justices just so he could stack the court with people who would agree with him.
