A commercial enterprise, for your edification, refers to an organized brothel, a massage parlour, a strip club; it is not the individual prostitute providing her services or a cooperative between two, three, or more prostitutes working together in their own space, where they're sharing expenses equally. That's what you're not understanding, and to say anything different would, in my view, be absurd.
