spread of STDs...
Regulate it then. Make the prostitutes come in for STD tests every week.
sex as a "commodity" rather than a loving act... females seen as "objects"... men not being able to deal with real women and the obligations that go along with sex... women involved having low self-esteem... and that's just for openers...
Sound like individual problems to me. It's not the government's job to stop individuals from making foolish decisions.
It is the job of government to "establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity..." When an individual's "foolish decisions" threaten justice, domestic tranquility, the common defense, the general welfare, or the blessings of liberty, then it is the government's duty to stop that foolish individual.
Now, as for the FSP, I wish it all the best of luck in its success. If all the anarchists are in one place, it'll be easier for the rest of us to get some work done.
