It helps to consider that the Ninth and Tenth protect "majoritarian" rights as well as individual rights from the federal government.

Majorities have no rights that any individual does not also have. Majority vote cannot convert a wrong into a right. It's just as wrong for 200,000,000 million people to enslave you as it is for your next door neighbor alone.

The Constitution doesn't, and can't, prevent every wrong.

Thanks to the Ninth and Tenth- and the whole concept of federalism in general- we have fifty states that can try fifty ways of dealing with an issue. What works best is there for all to see.
