That's not obvious at all.  Once you get near the eye's resolving
ability, further improvement buys nothing.  Not only that, but very
effective stereoscopy has been done with two 512-pixel square images;
pixel-to-pixel coherence makes the depth resolution argument less
significant.

Interesting point:  It was reported in the 1950's (when stereo
photography was popular) that something like 30% of adults have
defective binocular depth cueing.  Perhaps this helps explain why
stereoscopy keeps failing to catch on with the general public
(eyestrain brought on by defective techniques didn't help, either).
