Not to diminish your point at all: I think it's also just a fear that the fun or interesting part of the task is being diminished. To say that the point of programming is to solve real world problems ('productivity') is true, but in my experience it's not necessarily true for the person doing the solving. Many people who work as programmers like to program (as in, the process of working with code, typing it, debugging it, building up solutions from scratch), and their job is an avenue to exercise that part of their brain.

Telling that sort of person that they're going to be more productive by skipping all the "time consuming programming stuff" is bound to hurt.
