When someone includes "of course" in a statement, they are often on weak ground, and I do not agree that there is any law which makes it illegal to increase your tempo in the the hope of inducing a mistake. 74D7 prevents you varying your tempo for the purpose of disconcerting an opponent. None of the definitions I have found of "disconcerting" in the dictionary includes "inducing a mistake". I have never encountered a ruling for unduly fast play and 73D1 also makes it clear that it is not always required to maintain an unvarying manner. Fast play cannot (in theory) work to the benefit of your side, as there is no requirement on the opponent to play at the same speed, as mgoetze points out, so the requirement to be particularly careful does not apply.
Unless I am misinterpreting your post because I could not quite piece together the double negative.
That you have never encountered a ruling for unduly fast play does not mean that such rulings should not be made. Your last sentence is a bit disingenuous, since I'm sure you know that fast play can (and does) indeed work to the benefit of your side.
