Anyone with supernatural powers that takes that offer is a fool - their life would be effectively over. A person that could, say, see the future, is better off predicting the winning lottery numbers and sidestepping the almost certain involvement with government agents, or worse.
(Not that winning the lottery is statistically a good thing for one's quality of life either, which is a plausible reason that "psychic wins lottery" has never been a headline...)
