It's very, very impractical, but that's mainly because you listed things i didn't imply.
Drug addict - that's not something of essential relevance here. Being a drug addict doesn't eliminate a person's ability to choose a job, nor compromise their will. I understand precisely why you mentioned it, and yes, it can make someone's life a mess and drive them to do things they wouldn't normally do, but it doesn't in my eyes negate their ability to choose generally, especially considering the wide variety of possible addictions, many of which are not all that severe. This is an extremely important distinction because there's a vast difference between unhealthy scenarios (where you are having sex with a prostitute who is not particularly enjoying your company - but wants to be there to get the money), and between sexual abuse, where you are having sex with someone who
does not want to be there at all, but are being forced by their pimps, for example. Basically, i'm clarifying that i was not intending for my scenario to be quite that innocent, and that's because it doesn't need to be for my point to be made in the first place. A claim was being made that johns are entitled rapists, this is what i'm addressing.
Never having being abused as a child - that too was not something i was talking about. Most prostitutes may have been abused as children, but people who are abused as children are not necessarily incapable of making choices for themselves, or are compromised in that department. IOW, i was certainly not talking about a psychological history check. I was talking about measures of caution and resorting to certain means that may produce an incredibly higher possibility of avoiding any possible victimization, and, coupled with self-imposed boundaries in the sexual act itself, may minimize the possibility even further to the point where it's just as basic as many other risks we take in life in our dealings with others, or at least very close to it.
Those measures i'm talking about are what would make what you consider a coincidence more of a statistically higher possibility resulting precisely from those responsible and careful considerations before doing something like acquiring the services of a prostitute, and similar self-imposed standards undertaken during the act itself, to minimize if not outright eliminate the possibility of damage in some cases.
What i'm talking about is not stemming from pure theoretical thinking. It might be difficult for you to imagine a considerate John, but they do exist. My best friend who i've known for over 10 years (and who is not an entitled rapist) has acquired the services of prostitutes twice in his life and he has shared every single detail with me regarding those encounters, from his efforts in finding the right prostitute to everything that happened in there.
First, he sought prostitutes, the services of which cause as high as 7 times that of more regular prostitutes that can be sought through other, easier and much more convenient means. Second, they set the boundaries, and in one scenario, the prostitute had very specific set of things she would not do which would otherwise be considered very basic stuff, and he of course didn't do any of them (despite going there hoping to), she led things for the most, and he was as interested in pleasuring her as he was in pleasuring himself (but only because pleasuring her would make him feel like it was normal and more spontaneous).
I shouldn't share stuff like this, but in the other instance he also hugged her and more less was an emotional mess in there, which is why he was there to begin with.
Short version, as easy as it might to be to set ridiculously high standards and paint black and white portrayals of johns, in reality there are many exceptions to the also very true portrayals of slimey, scumbag entitled cockroaches. Some are just people in desperate need of sex and are unable to obtain it otherwise, for one and the main example i'm concerned with.
Some jobs require people to put their lives on the line for you, with ridiculously low pay.
