places a set value on something that many see as sacred; something that shouldn’t have monetary value.
I'd say it's the other way around - because it's labor that is (mostly) being performed by women (or stigmatized as something "only women do") it's considered to be of no value whatsoever. How many women do you know that performs work such as housekeeping, child-rearing and/or marital sex essentially at own cost because this type of labor carries no monetary exchange value in our society?
I'd say sex work falls into that category - but it gets stigmatized because sex work can actually allow women to escape such labor and not be locked into literally playing housewife to the capitalist mode of production (ie, wiping a company man's arrse so that he can concentrate on making capitalists richer).
