Yes should also say a resounding agreement to focus on the men here.
I'm not really that interested in individual women's choices unless they are detrimental to the women, I don't really look at any of this in terms of "choices" TBH. Men around the world want to have women (and girls and boys and men, in lower numbers) to wank over, watch, fuck, and so forth, and there will always be people to do that for them (for whatever reason). The question is how far do we want to normalise and legitimise this in our society.
I would also ask the question, of in terms of harm, say it is the case that none of this changes male behaviour towards others (overtly or otherwise), even then, what is the effect on females (girls and young women and women) of knowing and having it be obvious that this is the primary thing so many men are interested in about them, for plenty of them the only thing, and that a large proportion will behave in anti-social or illegal ways towards them? What effect does that have on the female psyche, how does it effect us as a group across the whole?
I suppose you could look at children and adults in different countries where different forms of sexual performance are normalised, including ones with or without money exchanging hands, and see how the female part of the population feels in terms of confidence, self-worth, what is important about them and so on. In "sexual performance" I would include both extremes of female dress (very skimpy / very covered) for example, different expectations in terms of grooming, whether sex encounter places are normalised and part of the furniture on the way to school and so on. I have no idea what the answer is by the way!
I mean if someone came along and said, it is a categorical fact that these things do not affect how males think, feel or behave towards females, and they have no adverse effect whatsoever on either the people performing in them or the female population at large, then I'd say well OK it's just me that doesn't like them then 
like I never liked Page 3 or anything where the female form was just presented for the sole purpose of sexual stimulation for heterosexual men.
But. But, while the situation is that so many men behave in an antisocial or illegal way towards women, with sex based stuff, is it OK to shove it in our faces as well? I mean, you're 14 you're walking down the street, you have a man say "show us your tits" and then 1/2 hour later you walk past somewhere that he can pay to get a woman to show him her tits. That validates what he did, doesn't it? He was only trying to get for free what he would otherwise have to pay for. Just chancing his arm. Don't ask don't get! & what's the harm... I just don't see how encouraging this transactional view of women's bodies and body parts can ever be a good thing for women and girls. Or even a neutral thing.
