""Pirating" is the act of acquiring a copy of a copyrighted work in a way that is contrary to existing law."

Okay - I'll bite. What does that mean? How does one acquire a copy of a copyrighted work in a way that is contrary to existing law? Or, alternatively, How does one acquire a copy of a copyrighted work in a way that is compliant with existing law? As a "Pro-IP Law" enthusiast, I'm genuinely interested - my layperson's understanding of the law is that it deals with distribution, not downloading.
