You're the one making the deal out of it.
But you brought it up...
An email might not, but an essay might. You can't compare a President's speech to an email.
My point is still completely valid. It all depends on the text vs. the speaker. You compared great speeches to an email. Might as well compare wedding vows to a text. Or a Richard Nixon speech to All Quiet on the Western Front.
When did you make that point? As in, before now? Never as far as I can tell.
In any event, it's not a very good point. In my example,
the content is the same. All that changes is the medium by which it is communicated. You can email Obama's best speeches to people, but they won't come across as well as they would if you emailed them a recording of his speech.
I'm not saying you can't compare the two mediums - clearly a novel is usually better read than heard, and vice-versa for political speeches. I just think that it's silly to say one is outright "better" than the other.
