I'm not sure it does, although agree that Holgate seems to be making multiple points
1) AWS is just one cloud, it's not even the biggest so you can't argue without AWS some of those things wont operate
2) Holgate's original argument was that Bezos was just a "middle man" who sold books and so doesn't deserve his wealth, what the original point was, was that he provides so much more. Holgate kept arguing that it doesn't matter as it's not a "primary or secondary industry" which according to him is pretty much all we need.
