Worst argument though. The building has already been paid for or has a lease. Using or not using it won't bring that money back. The only thing that can bring the money back is subleasing it. Even not using it saves some money (energy bills).
That's not how this stuff works. The buildings belong to people, ultimately most of them being to the oligarchs. Having a lot of people work from home will put pressure on real estate values so the oligarchs might see the line go up a little slower. So they put pressure on CEOs to keep people locked up in their silos. They're also easier to control that way.
