Wrong initial premise:

While peoples' choice is a combination of many factors, I would like to think that the popularity of the 35 / 2 IS over the other candidates is based on size, weight, price, and IS, and that these factors outweigh both speed and IQ since the 35 / 2 IS is "fast enough" and has IQ that is "good enough".

...

The 35IS IQ is good, not just "good enough". Why is that so dificult to fathom and accept?

In terms of speed, the 35 / 2 IS is a stop slower than the 35 / 1.4A and 35 / 1.4L II.  In terms of resolution, it's not as good as the 35 / 1.4A (until f/4, albeit pretty close by f/2.8), nor is it as good as the 35 / 1.4L II.  Specifically, at f/2, the 35 / 2 IS has almost a stop more vignetting than the 35 / 1.4A and 16% lower resolution in the center (but only 6% lower in the corners).

But, f/2 is "good enough" for many, if not most, the IQ is "good enough" for many, if not most, it has IS, is smaller, lighter, and costs less, making it the preferred choice for many. Why is that so difficult to fathom and accept?
