I can fully believe there are a number of sex workers who found RedBook truly useful, and provided an extra layer of safety and security. What I can't believe is that for a line of work that is inherently illegal there were not at least some people who had abusive relationships with people coercing or even forcing them into it. You seem to be suggesting not a single woman (or man!) who used RedBook was being exploited, even a small minority. I think you're being naive.
