I do feel like "Don't hate the player, hate the game" is used to shield folks from criticism about actively participating in a societal ill in exchange for money. I realize that sex work and its presence in society goes all the way back to antiquity, and technology is only going to make it more prevalent. Some folks with compartmentalized morality may as well think "Life is short. Why work a crappy 9-5 when I can make a ton of money doing this other stuff instead?" I get the appeal.
That said, if shame were brought back into the mix on a large scale, a lot of this profiteering would evaporate away, and push this industry underground.
