I don't disagree. The problem is that people are error prone, and excel doesn't value check. We had to build large BPM-driven processes in order to account for this. Also I don't want to imply that users got to test the system while it was being built. That would imply that there was a logical product development process in place, which for most projects, there wasn't. Users got something that had been frankensteined over the course of the project, and muckity-mucks wondered why projects and applications went stagnant because users stopped using them and went back to excel.
