Theft is when you take something from someone. As in, what you have materially gained, they have materially lost. Copyright infringement is not theft, and must be treated differently, because what you gain, nobody has lost; the supply is infinite. If you accuse someone of stealing the income, but they haven't gotten any money out of it, how does that make sense? What you're describing is a missed opportunity for a sale; had someone 'stolen' nothing and simply passed the product by, you would still not have made that sale and nothing would have changed.
