No, the problem is that the "edge cases" will swallow the rule if you make an exception for every instance where advertising is actually serving a purpose, but if you don't make those exceptions then you would have created so many new problems or require so many patches that each carry its own overhead and opportunity for cheating or corruption that the costs would vastly exceed the benefits.

Only it turned out to be an example to illustrate how patching the edge cases might be a quagmire.
