I am skeptical of the claim but not the conclusion. I take the claim anyway to be a bit of hyperbole to sell more books.
One of the biggest problems in law is what IT/CS people might call technical debt. New laws get added all the time while old, often-outdated or useless laws rarely get removed. The problem is that those old, even outdated and useless laws can sometimes be leveraged against you in new or novel ways, sometimes that the drafters of the laws never would have expected. Legislative intent is not always clear and not always decisive.
