“As in all voluntary exchanges, both parties benefit from such an exchange: Smith receives money, and Jones obtains the service of Smith’s not disseminating information about him which Jones does not wish to see others possess. The right to blackmail is deducible from the general property right in one’s person and knowledge and the right to disseminate or not disseminate that knowledge.
