"I have emphasized that a difference between black-market crimes and
most others, like racketeering and robbery, is that they are “crimes”
only because we have legislated against the commodity they provide. We
single out certain goods and services as harmful or sinful; for reasons
of history and tradition, and for other reasons, we forbid dope but not
tobacco, gambling in casinos but not on the stock-market, extra-marital
sex but not gluttony, erotic stories but not mystery stories."
