One more thing. There is nothing natural about using prostitution as a metaphor for 'any act undertaken for purely monetary motive.' You don't really understand the nature of capitalism and wage labor if you think sex work is a 'natural metaphor' for 'any act undertaken for purely monetary motive.' Many workers, not just prostitutes, receive pay for 'servicing pleasure.' And many (if not most) acts are undertaken for purely monetary motive under capitalism. Think Wall Street.
