It is wrong to use excerpts from the introduction to justify ones position without considering the context and overall tenor of the text. The introduction begins by quoting the Scope of the Laws as an indication of the Commission’s intent, and then provides further guidance for the interpretation of Law. This guidance offered for the interpretation of “must”, “should’, “may” and “does, is given in context of the text which precedes it. It is not intended to supersede or contradict the Scope of the Laws, but rather to clarify the Commission’s intended meaning.
If the Laws are primarily designed not as punishment for irregularities but rather for the rectification of situations where non-offenders may otherwise be damaged (and it’s clear they are), it then follows: Assigning procedural penalties for violations of procedure which are do to error, inexperience, or (to a lesser extent) carelessness, and which do not require an adjusted score for any contestant, is a practice inconsistent with the Laws of Duplicate Bridge.
Assigning procedural penalties for any violation of procedure which uses the words “must“ or "shall" would be an irresponsible practice, based on an obtuse interpretation of the Laws. If we were to adhere to this practice, Directors would assign PPs for violations of Laws such as L44C

In playing to a trick, each player must follow suit if possible.
That position is Bananas!! Violation of this procedure is addressed by Laws 61-64.
Or L50D1

A major penalty card must be played at the first legal opportunity.
Any failure to comply is subject to rectification under L52B. Again assigning a PP for violation such as this is indefensible.
Many violations of the Proprieties should be considered serious enough to merit a PP, but (yes it deserves to be said again) it is inconsistent with the Laws of Duplicate Bridge to assign PPs for violations of procedure, which are do to error, inexperience, or carelessness, and which do not require an adjusted score for any contestant.
It has been noted that the Scope of the Laws does not preclude the assignment of procedural penalties. That is indeed true; but it should also be noted that there is nothing in the Laws of Duplicate Bridge which should preclude the use of common sense.
