Could you please explain how is it that somebody gets hurt with piracy?
For me, the situation is quite different. I wouldn't say that piracy is what makes money to move, but technically speaking, I see nobody's assets being lost because of the simple fact that I have copied something he or she has ever created. What is more, this creator might never realize it.
I am truly conscious that there is a problem with digital media related with piracy, though. I don't have a solution that would fill the hole, but I don't see that DRM nor laws such as the DMCA are the way, honestly. In copyright-based income, it has to be taken into account that copying the work has a near-zero cost. That said, it's logical that people try to get it free. There's the problem. Now, would you say that when people do copy it, you actually lose something? I doubt you would. Probably the price of the license has to be so low that copying it illegally simply isn't worth. After all, if the application is good enough it has a big chance of having many sales. This is not the ideal solution but neither is DRM. With DRM, besides the fact that it's often an obstacle to legitimate users, after the way to circumvent it has been found piracy will arise shortly. Therefore, an incentive to copy the software.
I leave the problem open, as I said I had no solution to offer, but I don't agree with your arguments.
