But I acknowledge that there may be edge cases. My point is that the existence of edge cases does not mean we should permit the harm to continue. Those specific edge cases can be identified and patched. My suggestion is a hypothetical example of a potential such patch, one that might possibly be a net benefit. Maybe it would actually be a net harm, and the restriction should be absolute. The specifics don't matter, it's merely an example to illustrate how edge cases might be patched.
Your objections to this hypothetical example are nit-picking the edge cases of an edge case. They're so insignificant in comparison to the potential harm reduction of preventing advertising that they can be safely ignored.

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