The GP's point is fair, though. Money is fungible, which is just another way of saying that it has no color. Anti-money-laundering schemes are essentially DRM for money.

Now it is my personal and completely biased opinion that money laundering and tax evasion are very big problems affecting society negatively, while copyright infringement on-line is mostly a non-issue due to IP laws being abusive; still, while relatively different in importance, the problems are still similar in the way GP describes them.

(And in both cases you learn that color is very important to the law.)
