It's not exactly coordinated. Powerful businesspeople usually own real estate, it's great for financing new ventures and so on, and they have habits. They go to clubs, golf courses, rather exclusive hunting trips and so on, where they meet other people with power in business. And they talk, speculate on the future and develop a community.
A community where they go looking for contacts when they need something, like a public affairs firm for pushing political buttons, or a real estate investment to put a big payout into, or whatever. If you are in this environment and fuck around you'll make enemies. People won't recommend you as a public affairs customer, won't tip you off on good investment opportunities, might start to talk shit about you behind your back.
Undermining the value of real estate can make these networks and communities a serious hazard to your business. And undermining the value of office estate means you undermine the really tasty cash cow in real estate, residential properties within commuting distance. Enforcing commutes to offices means that people will pay a premium to shorten the commute.
