A friend of mine who has a political role in a country other than our own was describing to me her battle on behalf of free government health care for prostitutes. She maintains that she is doing this on a moral as wall as a pragmatic basis. The efforts of the Catholic Church to thwart her initiative were viewed by her with disdain.
I made the following points in my response.
1) I am not convinced that prostitution should be illegal, but I think it should be against public policy so that we don't get absurd anomalies like the German government denying a woman unemployment benefits because she had a job offer - as a prostitute - that she was not accepting. I would be perfectly content to live in Nevada where the populace has deigned to allow prostitution as a legal enterprise subject to licensing and registration requirements.
2) However, we must also recognize the right of polities to place transactions of that nature outside the law. The vast majority of localities have exercised that right and most of them enforce those laws to some degree.
3) Inasmuch as this is an illegal activity in these venues, it is inappropriate to attach any special rewards to this activity. The conferring of a free health-care program is a sizeable financial award.
4) Furthermore, this constitutes a benefit attached to this field that is not present in waitressing or house-cleaning or other things that unskilled people do to scrape by until they can better themselves. So besides for the reward for those already engaged, we are now offering an incentive for those who are considering.
5) The same set of inferences that are drawn from illegality as a profession (contrasting prostitutes to waitresses) can be drawn from the conflict with social mores (pitting prostitution against marriage). We cannot give advantages to a prostitute that we are not giving a wife.
6) In general, there is no such thing as "free" health-care. This is a euphemism for taking money from taxpayers to give to others. This means that we are making those waitresses and wives pay taxes so the prostitutes can receive a benefit that they do not. This is a palpable absurdity.
There are more details that could be added to this, but for now this should suffice to the case.
