Your model is nice, but it is missing one important step: At the beginning of the experiment, all people who were not at the bottom of the company pyramid are shot, and their roles are filled by randomly selected remaining employees. So the company starts with nobody in the management having any idea about anything, and it takes a few decades of trial and error to regain some knowledge about how to run things. In the meanwhile, many employees starve to death. At the end, Wallmart finally regains its former functionality. The management proudly opens the windows that have been locked for decades. On the outside, they see drones flying everywhere, a personal teleport at every street corner, and rockets regularly flying to Mars. In despair, the entire project is abandoned.
