I think she's right to say there isn't, ethically speaking, a real line between pornography and prostitution.
On the other hand, there is legally, and that does make a difference in practical terms. I would support bans on pornography, but they would inevitably start to impinge of some mainstream tv content, maybe some of what happens in live theater too. I think that would likely be better overall for actresses but I suspect it would be difficult to get widespread agreement.
