A person whose body is objectified and exploited by countless selfish men do not have to "feel" exploited to be exploited. It's simply a fact, regardless of whether the person volunteers to be exploited.

Porn users and addicts may not realize in the moment how harmful porn consumption is to themselves, but that doesn't mean it isn't harmful. All they know is that it feels good right now. And they can even say (in a way) that they are not "forced" to consume porn; they volunteer to do something that damages them. (In reality they are ensnared.)

Likewise, the porn stars who are sexually exploited may not realize for a time how exploited, objectified, and used they are. They know they get paid well, but they don't always understand how their sexuality (a core part of the human person) is being cheapened and their soul damaged. I believe they realize it at some level, but they justify it because of the money.

Morality is not determined by financial prosperity (wealth can be very deceitful). And morality is key to living a free life. Addicts and prostitutes are not free; they are enslaved. We should discourage the enslavement of their souls.
