The thing that bothers me about the comparison between WeWork and AWS is that Amazon builds, owns and operates AWS data centres. Wework largely doesn't own the properties. I think that's a pretty important distinction.

Also, whilst a normal business can't really build a "AWS competitor for Chicago" the "A WeWork competitor for Chicago" seems like a much bigger threat. If the only way that WeWork can win those situations is by running at a loss in competitive markets and then monopoly pricing in other markets you've got two choices: Either they'll never make money because they'll always be loss leading, or they're facing being broken up by a regulator.
