I don't see overturning Roe regarding privacy. I instead see it as reversing an activist reading of the 9th via Griswold, which turns the core meaning of the 9th on its ear.
I agree there is a right to privacy. However, it is not a federal perogative to enforce that right. The 9th simply tells the feds they have no say in the matter, other than aspects of privacy addressed in the 4th and 5th.
"The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people." - The Ninth Amendment
It simply says that just because a right isn't enumerated doesn't mean it doesn't exist. Nothing more, nothing less.
