Olive oil can easily sustain 160C for hour long period of time. You can use it for saute and pan frying. What you are refering too is deep frying with temperatures above 190C. That is what the consensus is, also my personal experience: it smokes really fast and tastes rancid.
I've had some smoking and a bit of rancidity using olive oil to do roast potatoes at 450F (230C) - 400F and lower usually works no issues.
