Eh, but even some of those reasons can be absolutely plausible, for instance the theory behind RTO being about middle management trying to justify their existence, because most middle management positions are just glorified babysitters with too much power and time on their hands. Another plausible one is the narcissism of the executive class, there's plenty of executives writing about how their "people" provide them with "energy" and that they feel lost without their involuntary audience. Then there's the plausibility of the point about property values, companies that own their properties understand that the property itself is an investment, and in business your entire goal is to reach that almighty ROI, return on investment, so not only do empty unused offices harm that, but so do falling property values.

There's almost always an inkling of plausibility in any theory, that's one of the reasons why so many people fall to the attraction of conspiracy theories, but at the end of the day you have to remember that these are just people, and people are often selfish and not always selfish for the same reasons, we all have things that are more important to us than aren't as important to others.
