Why is it that underage people don't have any power of consent, while overage ones do Marie? Do we become magically invested with the power of choice aged 16?
Sorry - but why is OK for anyone to be able to be put into the position of having to do this for cash?
I think very few people defending the "right" of a woman to be a prostitute would choose to be one themselves. Otherwise we'd all be making a bit of cash on the side.
(Of course, they're different - they just don't care, or they love sex, somehow it doesn't do them harm even though it's not something we'd do, or they're already damaged anyway, why not? Let's not treat them as children.)
Meanwhile we know that people's "choices" are actually the result of their situation from birth to adulthood and beyond - there are a million factors which shape us and the way we "choose" things. Personally I don't believe we have that much free will at all, a lot is determined or caused by our circumstances. Person A raised in an abusive household will have less "choice" than Person B in a loving one because their entire mindset and life are skewed from day one.
I also agree that if there are no checks on behalf of the punters, they can they never be sure the woman has consented in any way, which makes them implicit in the whole culture.
