I've never heard a good argument against prostitution. The arguments that I hear are against trafficking, rape, child molestation; which are all non-sequiturs: true and valid statements that do not support the argument itself. Can anyone here argue against prostitution per se? I'll listen.
It's said to objectify women. More specifically, the Johns are treating women's bodies as something that can be traded commercially. The more that is normalised, the more it damages all women - not just prostitutes. If you don't think objectifying women harms them, then that's not a "good" argument, I guess. FTR, I'm against laws controlling consensual sex. Not all harmful behaviour should be criminalised.
To accept the argument at all is to agree with the original premise. Which I don't, even assuming we could come up with a definition of objectification we could both accept. But... let's give it a go.
Let's posit there is a thing that happens called objectification. Whatever it is, it causes men to treat women badly, specifically, causes unwanted advances and sexual harassment.
A man somehow catches this because he can pay a woman to give him an orgasm. He doesn't even have to actually do it. Just knowing this is something he can do is enough. Then he goes out and... what? Expects to be able to pay every woman for orgasms? He won't treat his woman boss with respect? I'm trying to understand the mechanism here.
Does this same phenomena happen in any other arena of life? Is it a kind of bigotry? Does bigotry operate a similar way?

Sex workers are "selling their bodies" no more than your local bartender or barista does. Sex workers provide a service no more magical than they do either. If you were to expand on this "selling their bodies", I think you will find that it is meaningless.
So, no, I don't think it's a good argument at all until we can demonstrate that "objectifying all women" is something that happens when prostitution is legal.
