The same place the right to own private property is.
Privacy of ownership, the right not to have one's property seized by the government (though Kelo has issued a repugnant challenge to this right) is far different from the "privacy" to do absolutely anything one wants. "Privacy" as established in Griswold refers to sexual relationships and to the life or death of the unborn. Since people are not property, the right to private property is non-applicable here. The post-Griswold sort of "privacy" is nowhere included in the Constitution, and has manifested itself in ways that openly violate our founding document.
