You are reading too quickly.Gen perhaps it is because I'm reading quickly but this sounds more like an advocacy for making prostiution illegal than anything else.
Basically, there are two main groups of feminists doing work, research, and advocacy around sex work: the anti-prostitution/anti-trafficking group, and those who advocate for the rights of sex workers and for the transformation of the sex industry, mostly by calling for a decriminalization of sex work, the recognition of prostitution as legitimate work, and for an extension to sex workers of the social and labor rights and protection generally granted to other workers.
One of their main argument in favor of the transformation rather than the abolition of the sex industry is that the abuse and exploitation of sex workers isn't inherent to sex work, but rather conditioned by the moral and legal constraints associated with the industry which puts them in vulnerable position. They also suggest that slavery-like practices and trafficking in women are the result of economic, political and gender inequalities, rather than being inherent to or the necessary consequence of prositution (as the anti-prostitution/anti-trafficking advocates suggest). In addition, while trafficking and slavery-like practices are commonly associated only with prostitution, these feminist and sex workers organizations emphasize their existence in a variety of other labor sector, such as domestic work, farm work, and factory work. As such, the critique they direct at the sex industry tends to distance itself from moral or emotive arguments, and to focus on the social, political, and economic conditions that make these exploitative practices possible.
For instance, they point to the lack of viable economic options, which restrains women from choosing the terms and the conditions under which they want to work; to the exclusion of sex workers from society and the denial of their rights, which puts them in a position where they can be abused with impunity (by clients, pimps, and the police); to the criminalization and other punitive or restrictive measures aimed at abolishing prostitutions and the sex trade (including restrictive immigration politicies) which push sex workers further into marginality and create the need for prostitutes to require the protection and assistance of pimps, smugglers, or agents who take advantage of their vulnerability to exploit them. Accordingly, those feminists and sex workers believe that the only way to fight the abuse and exploitation of sex workers and to combat the trafficking in women is to politically and legally recognize the existence of prostitution and to guarantee the human and labor rights of prostitutes.
