It is briefly mentioned in the notes at the end that nobody has seemingly ever been prosecuted for this, and the laws are primarily aimed at institutions doing shady stuff rather than individuals wanting to feed their friends potatoes. But yes, the focus definitely isn't on that side of things.

I don't think it's fair to call that a deficiency, though; both the letter of the law and the practical applications are complex and interesting topics in their own right(s?), and either could fill a lengthy article as we see here. Both are welcome! One doesn't preclude the other. I would be interested in reading an article covering what you describe too.
