You've made no attempt to even find out how many adult bookstores there are in the U.S. You have only relied on my sources which you yourself impugn. You don't even know when this article was written.
You mean when debating you we should NOT rely on your sources when arguing against your position?
Later you posted another source that also proved your original source to be a lie.
You have 2 options. Get better sources or quit posting on FR.
The "20 times the number of adult bookstores" quote you cited comes from an article entitled "The Business of Pornography", written by Eric Schlosser, and published in the February 10, 1997 edition of US News & World Report.
Obviously, the number will be dependent upon how one defines what constitutes an "adult bookstore". If the US News article is accurate, that number was approximately 1,250 in 1997. Since I have no idea how the author derived his figures, I cannot comment on their accuracy.
