The point is to prevent "tearing". A lot of effort has been put into solving that problem.
If the pixels were updated in some random or semi-random pattern on the screen it would probably be unnoticeable, but I suspect that either a lot of architectural changes would be needed both in software and hardware, or you would effectively have to achieve a 480Hz full-screen refresh rate to achieve it without doing things like attaching an address to each pixel output so the rendering device didn't need to assume sequential pixels should be drawn sequentially.
