Not everybody thinks in the same way. Some, maybe most people benefit from intuition pumps such as analogies. Good analogies clarify the point, poor ones obscure it.

I definitely agree with this, but I think a "good analogy" is really rare.
In this case, I think that the analogy just obscures the main point about copyright. I think the original comment would have been stronger by omitting the analogy and just discussing where the legal responsibility falls.
In almost every case an analogy is made, people discuss the validity of the analogy over the actual point of the comment (I'm guilty here too! my comment ended up being about the analogy rather than the main point).
