Dworkin was a big critic of pornography, claiming it caused rape and subjugation of women. While there are undoubtedly some women in porn against their will (or verging on doing it for lack of better options (ie, "for the money")), this point of view completely ignores women who are aware of their options, but choose to do porn and see it as an issue of "their body, their choice".
There is enough porn produced already so if the production ends today there's enough already for most of people.
Concerning distribution: is there anybody stupid enough to ask for an never-ending, positional "war on porn"?
As if wars on drugs and on pirates wasn't enough
I never paid much attention to Dworkin's arguments, but I wouldn't be surprised if there were people interested in a "war on porn". Never underestimate the human capability to formulate simple "solutions" to complex "problems".
As for the production aspect, as I said, there are women in porn who view it as a women's rights issue, ie who is to say what women can and can't do with their bodies.
