Overnight, i realized that the grocery store example was probably a bit lacking and incomplete.

Some religious and legal societies incriminate prostitution. If a man engages in prostitution, he can get into legal trouble. This is especially true with child pornography and sexual exchanges with minors. Thus local sexual services are discouraged and scarce.

So some women, seeing the lack of local sex services, decide to sell such services through webcam; even though such services aren't legal and can get a man in legal trouble. I've read many articles about men arrested for engaging in sexual activities with minors and prostitutes.

thus, those women are taking advantage of a shortage of sex services in an area via providing the services online.

In a business sense, they are taking advantage. they are making use an opportunity to make money. And just like any other business, technically nothing is wrong with that.

On a side note, morally and legally, men like skibum801 and james could be endangered by the business, if those men are in a society that outlaws prostitution and have a strong sexuality.

It's like a man selling street drugs to women in his area. He takes advantage of their tendency to abuse substances, even though he knows that they can legally get in trouble for being associated with street drugs in certain situations.
