it's not that i'm going to argue with a "sex worker" that they don't own their body or they shouldn't have control over it, it's that i'm going to point out very strenuously that if they think that legalizing prostitution will give them more control over their labour rather than less control over it then they simply don't understand the reality of commodity capitalism very well.
i have said this over and over again, and i'll say it again: the legalization of prostitution will result in the reduction of prostitution to salaried wage work, at a minimum wage. being a prostitute will become just like getting a job at mcdonald's. you'll need an interview with a boss, and potentially a uniform picked out by the company. you'll report for a shift work in your room, and if you're lucky you'll get paid overtime. and, then, you'll probably want a job at mcdonald's, instead.
if you want to maintain control over your body and your labour, you want to find ways to inflate the price of your service, which means keeping it scarce, and on a black market.
the people that actually benefit from legalization are not the prostitutes, but the johns - and the pimps. and, the ancap fantasy reality that suggests otherwise is not any kind of meaningful feminism, but just another utopian application of market theory that anybody with any basic sense should be able to see through pretty clearly. when you increase the supply of something, while keeping the demand steady, you collapse the price. and, when you open the industry up to corporatization, the result is that independent contractors have little option but to become salaried employees of a capitalist class that then takes control. you don't get the choice, either; the market forces you into accepting a wage.
that is capitalism. your ancap free market fantasy reality is not.
so, my argument is that you don't understand economics very well, and need to rethink what you're proposing in order to get what you want. what i'm not doing is arguing with you about what you want, or questioning your agency in how to get there.
if you want more freedom over your body and what you claim to be your work, legalization is the last thing in the world that you want; it will give you the exact opposite of that, and play directly into the hands of the people you're trying to protect yourself from.
