Doesn't the fact that prostitution is illegal imply that pleasure is not a considered a legitimate and significant moral good? Prostitutes are said to be people who provide nothing of value to society. Nothing of value? Really? Perhaps this is because our society has a deontological system of values? In a utilitarian standpoint wouldn't it not only be moral to make prostitution legal wouldn't it in fact be extremely immoral to make it illegal since sex is extremely pleasurable and in a utilitarian calculus more pleasure equals more good?
