I hear what you're saying, but I think that the writer was correct to bring up the fact that a lot of people might not fully understand their own feelings about porn or by extension, sex work in general. There are a lot of non-profits out there that collect data on sex workers of all kinds, but I think it's easy to accept that data as "true" even when we don't question why the data was collected, or the mission behind those non-profits. Sex is complicated stuff and it's not easy to understand why someone might want to profit from their own sexuality from an outsider's perspective. Yes, some people are coerced into sex work, or tricked into starring in porn but to me, that's a very compelling reason for sex work to be treated like other professions so that people who work in sex industries can be sure to receive legal and social protections from predatory agents seeking to exploit people. Of course, that's easier said than done.
