Your first paragraph gives a great demonstration why the GP post thinks that most conversations about peak old "disasters" are silly, and your second paragraph and third paragraphs admit as much, despite you leading off with it not being so unbelievable.
Your comment basically reads "Peak oil isn't ridiculous if you believe the entire globe is so unaware of what they're individually doing that they're going to run out of oil without any warning their own wells are going dry, because the wells aren't operated collectively, so we require ALL the operators do this at the same time in the same manner. Also, there isn't going to be a decades long transition because all of these people are on exactly the same schedule because... er.... Also! No one will switch to other power to lower the demand on in-the-ground oil because as I just said, it'll all happen at the same time incredibly fast."
I mean, I guess you're welcome to believe it, but it relies on several facts that just aren't true, and is too simple of a model to fit if those facts are included.
No, you require that /everyone/ be short sighted and at the same time, not actually looking after their own interests.
While I do agree that people are generally selfish, my experience with various executives across industries is that they're hardly stupid, and that there are many smart people working on the world's problems, even if only to make a buck off it.
More to the point, I only need to think that a one-in-a-million person cares to do anything about the "peak oil problem", is intelligent, and is in a position to do so in order to believe that there are 7,000 people working actively on it.
There are only a few hundred major oil companies globally, meaning that each one will like have a dozen (or more, for larger ones) people who are intelligent, highly motivated one-in-a-million people working on it.
I think you greatly underestimate the number of people and the scale at which humans currently operate.
It would be borderline impossible for them to all be short-sighted in the same way, at the same time, given the sheer number of people who are working on the problem, particularly given that there's a strong economic incentive to not make that mistake.
tl;dr: No, your belief requires that literally everyone in the oil industry thought process (tens or hundreds of thousands of people) not be looking after their own self-interests if they're driving the bus off a cliff, and that they will all do so in the same manner and at the same time.
If people who possess oil reserves are short-sighted and selfish actors they will certainly try to hold on to those reserves in expectation of large future price increases.
