I think you totally missed the point of the article. The doctor there did what you advocate, it's just that he doesn't consider that doing everything they can.
In any case, how exactly do you know what they didn't do that they could have? I don't see where you get enough information to derive any such conclusion. Considering that the doctor writing the article was just an intern, chances are he doesn't know everything they tried; how can you possibly claim to know?
I can claim to know because of all the comments in this thread, because I've had loved ones get terminally sick, because I know what every doctor says when you ask them about this, and the stark reality is it's more about the masses than it is about the individual.
We literally can't try everything on everyone because that'd lower the average level of care overall, not to mention the ethical concerns over experimental treatments that haven't been sufficiently tested.
You can interpret the text however you want, it's still entirely topical to call out the medical profession on the false notion of death as peace that they're trying to sell us for their own sakes, at our expense.
