Whichever way you look at it, the Pi2B is really cheap for the performance, and the Zero is really cheap for the performance.
Absolutely agreed. And if someone wants or needs the capacity or performance of a 2B there is little doubt that is what is best to get. It is also what I would recommend for anyone starting out with a Pi if they can afford it, a B+ if on a lower budget.
For many people though the power of the 2B is not required and a B+ will do just fine, and even the A+ or Zero. Paying more for something one doesn't need or want is just a waste, taking money which could be better spent on something one does need or want.
The bottom line is that it isn't people who want a 2B or would be better off with one who are the market for Zeroes; it's the people who want Zeroes who are.
There are some who want more on their Zero, would like it to be a cheap A+, B+ or 2B, have Wi-Fi or ethernet, camera or display connector as standard, but most want the Zero for what it is. It might be nice, and would be nicer, with more but it's not essential for most people.
I guess it's simply not seeing how the Zero is seen by others which makes it hard to fathom why there is such a demand for it.
I suspect that's mainly because Pi computers are still perceived as computers for facilitating education, the Foundation are still an educational oriented charity, even though Pi computers are mostly used as application platforms, and the Zero particularly fits that niche.
