The child labor analogy doesn't really match up here. The parent comment is saying that if prostitution is legal but hiring prostitutes is not, then people will only hire prostitutes in areas where law enforcement is weak. A comparable analogy would be that if laboring as a child is not criminally illegal (which it is not) but hiring children as laborers is illegal (which it is), then the people that hire child laborers will be doing so in areas where law enforcement is weak. This seems to be both a pretty apt analogy, and also seems to be clearly true in the child labor case.
