On the whole an excellent article.  I was particularly heartened by this:

Into all this doom and gloom I will insert the tale of New Zealand, where, since 2003, prostitution has been legal, but coercion is illegal, as is immigration to perform sex work and investment in the sex industry. In dialogue with prostitutes, the government developed a health and safety structure for the industry, meaning that anyone selling sex has a legal responsibility to use a sheath. In 2005, someone was even charged for slipping the condom off without a prostitute's knowledge. A report commissioned five years after the legislation showed that the sex industry still had many problems ? stigma and violence among them ? but there was no increase in prostitution, and sex workers were more empowered.
