Yes, having the freedom to sell your body on prostitution websites is more freedom. I do not know what the rest of your comment means, but mine is pretty clear that not having to rely on a man to earn money and then give it to them is more independence and freedom than depending on a man to give them money.
PS Isn't it funny that a women "selling her body" on prostitution websites is bad, but a man (or woman) selling their body doing back breaking work for menial wages is OK?
