Thanks for mentioning 'public nudity' as a religious concern. I know it's an obsession of Christian history, but it's really unclear where the Bible is even troubled by it. Prophets seem to often be naked, and Jesus is often naked. I'm not seeing that Jews were troubled by public nakedness either, or at least the Dura Europos fresco wouldn't suggest so.

Since nakedness is the Edenic state, I'm not sure why the Bible isn't read to sort of encourage it.

But as to the issue of ownership of humans, I think you're mixing in the issue of human ownership, i.e. "patriarchy," where the Bible is concerned mostly with *divine* ownership. In the Judah and Tamar story, Judah doesn't own himself. If he inseminates a woman from another religious system, he's not a free being. He's committed a violation because his lineage belongs to YHWH.

But when the messiah is produced, the genealogies stop. The control over Jewish reproduction—in the Christian reading—stops. And Gentiles were never sexually regulated to begin with. Jewish law is never extended to non-Jewish people.

Unless one tries to argue that becoming a Christian somehow brings a Gentile under Old Testament regulations—which no Bible reference seems to help explain—it's unclear how any of the OT stuff is even relevant. Christians would not be expected to have known the OT. They didn't read it, or have it read to them. No NT reference encourages the OT be read. The later Christian fascination with the OT, as if it expands and corrects the teachings of Jesus, is kind of puzzling.
