There's plenty of actions that, while not illegal, decent people can find distasteful enough to shun people who engage in them. Using your money -- whether directly enough to be considered prostitution, or a little more indirectly -- to surround yourself with women who are 18 years and 10 minutes old is legal but more than a little gross. And extremely gross if they had a choice in the matter roughly equivalent to the Anatole France quote: "The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges, to beg in the streets, and to steal bread."
