The Ninth doesn't mean "you can't regulate anything we didn't mention".
It just says that any mere omission shouldn't be construed to mean anything. The lack of an enumerated right to privacy doesn't forbid the courts from deciding we have one.

"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
The Ninth is a reminder that the Tenth has its limits too.
