In that case, a large proportion of sex in dating or relationships isn't "genuine intimacy" since many people are fakes, lie to each other, use each other for sex or other things, etc. I find sex work to be more "real" than a lot of so-called "real relationships" where people are manipulating each other but because they're not paying for it (directly, although they may be paying for it in other ways) we consider that to be a "real relationship". I'm sorry, but that's a crock.
Also, hiring escorts doesn't necessarily have to be about sex or primarily about sex. Some people hire them to be dates, some people hire them because they want someone to talk to, etc. There's even escort services for disabled people who otherwise wouldn't experience those things. Some people become repeat customers and form a sort of bond with the sex worker. Should they be vilified over that? Geez, sometimes you just want to be given a, more or less, guaranteed nice time and not have to worry about all the bs games that people play.
