Your money laundering analogy is apt. I know very little about that topic, and I especially don't know how much money laundering is really out there (nor do governments), but I'm confident that a lot is. Do AML laws have a chilling effect on it? I think they must, since they surely increase the cost and risk, and similar legislation for scraping should have a similar effect. But AML is a pretty bad solution to money laundering, and I despair if AML-for-scraping is the best possible solution to scraping.
