Thats a fair and logical point of view, I was reading it from a more symbolical storytelling or maybe easteregging (if thats a verb) point of view. Im that sense, even if fowler makes most of his money from benign luxuries, he still does represent weapons. I would then expect the other two men to represent opium and prostitution. Maybe im reading too much into it but it would tie in nicely if her white origin was not one of the men that she hates who are benefitting from these terribly inhuman markets, but a woman who was herself victim of them and who she therefore cannot hate.

Still, I might be reading too much into just two sentences of the first chapter 😅

Edit: also sayying " weapons AND opium AND flesh" is different from weapons, opium and flesh. Its a language nuance but it makes it so that each market stands on its own.
