Why do you assume people behave this way, when there's every indication that human's don't behave with "utopian ideals"? This is exactly why BI is such a terrible idea, along with communism, socialism, and free-market capitalism. The system we have now works "pretty-ok" which is leaps and bounds better than this theory and others which require people to act as "honorable actors".
