The point is, these people are stealing already, and the difference in the ease of stealing using what's already available and the ease of using Amazon is not that big of a difference, and the current stealing techniques don't cost a monthly fee. I don't see people switching to Amazon for all of their theft. As someone pointed out, Amazon could easily monitor this behavior and turn these people in. At least with the current theft you aren't being watched by a big company with a vested interest in you paying for your music.
