I think the complication emerges in the oodles of ways that "porn" can be produced. A kid goofing around with a webcam for bitcoin is really different from a sex worker in Thailand.
The porn industry thrives because there is a market for it. The contention that it enslaves is only right some of the time. Unfortunately, it's really hard to make it right none of the time.
As for the "encouraging" wife or daughter, you're right - but nor do I want my daughter to get an abortion, smoke, or attend the byu.
I really do feel that the issue is very complicated, but I'm getting close to "doth protest too much" territory.
