If I marry, all I have to do is clone my wife and dissolve the original in acid. Then I let the clone assume the life of my wife but also make it clear she would lose all of it if outted as a clone.

Then when she cheats on me or deny sex, I just kill the clone and make the next one watch. Again her choices are to die painfully, to live with no personhood rights, or to be my “loving” wife.

Seems like the perfect plan for a stable marriage.
