I never voiced my attitude towards legalization of prostitution. I addressed very specific weak argument.

Sorry, if you found my comment rude, i assure you that this was not my goal.

You used abortion there. I don't think we could get a consent from fetus, law just assumes that female parent have a power over it's life until some development point.

People consensually participate at gambling, dueling, pyramid schemes, become criplled drugs and alcohol addicts, selling themselves and they family to slavery, do suicide.

Nor consent, nor something being an old and persistent part of the human culture are good reasoning.
