This is ridiculous. I'm "economically" coerced into working every day (i.e. if I don't work, my employer will stop paying me and fire me), but that's completely distinct from slavery, which is work forced using physical coercion (or threats of physical coercion), and is illegal. What you're describing is essentially prostitution. While illegal in some jurisdictions, it's far from rape.
