That's probably because you've never worked as a projectionist. Films are rather routinely butchered these days in the average googolplex. Storaro is simply suggesting a system that would prevent this kind of butchering. Granted, one of the results is that Apocalypse Now will lose some of the sides of the image, but cinematographers routinely compensate for this kind of loss by composing their shots more flexibly. Take any 2.35 or 2.40 film made in the last 10 years or so and you'll notice that the extreme left and right edges are scarcely used, since the cinematographer knows these will be the first to go when the movie hits theatres.
Does this mean I'm justifying Storaro's promotion of Univision? No; it merely means that I can see where he's coming from, based on my own experience.
