Legal prostitution better protects prostitutes

What is the crime of prostitution? People have the right what to chose how to use their body, whether for fun or for riches. Criminalizing prostitution expose prostitutes to an unsafe work environment where they are exploited by their "protectors". Regulating prostitution like any other sexually explicit business would better protect those who chose to use their body for income - just like runway models, many Hollywood actresses, and many pop stars on MTV.
