| I agree that the essay requires too much training, but it also gives you awareness of how to formulate a decent argument when you don't have a month to do it. It's a very helpful skill, few of us will have to write long, edited and reviewed papers in our non-academic life, but almost all will have to argue for or against something in a few well, if not superbly written paragraphs.
“Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.”
