That is like saying that the stock cylinders are fine, why not run them? The answer is that as we modify engines to create more power and stress, other components need to be modified as well to accomodate.

Your point is well taken, though. I do have a 2 core cross flow 24 x 20 aluminum radiator, and dual electric fans with a proper shroud. I need a new water pump, and I have determined it is cheap insurance to buy a quality water pump for many reasons. Despite the arguements otherwise, a high flow water pump will aid a bit in cooling. So it can't hurt if I need to buy a water pump anyway.

Because I drive my Jeep offroad, both in low speed situations, and on the dunes causing continuous high stress on the engine (excessive heat with less ariflow than highway driving), all additional cooling I can get is helpful.
