You're correct, laws on the book can be used as prescedent, but the basis/ruling for the laws you cited is property rights.
That's why I would consider these laws as "moot."
Citizens are not property. That's why I doubt anyone would go into Federal Court and argue the Fugitive Slave Law or Dred Scott to support the governemnt's right to "grope" airline passengers.
By legal cavil we must not let our government place upon us captation. Cavilis a captious are all the chains of bad legislation layered with iron link nets of stare decisis when they come to tell us that bad is good. That indecent pat downs are a public good and necessity, that homosexuality is a right, that marriage is foolish, and perversion proper for all.
