Seriously. Every job I had, the C-level were all about flexing the size of the company.
One Fintech company I worked at got a giant skyscraper in front of city hall as a Fuck You to the mayor because they had beef with them a few years back. Another tech company constantly bragged about how much square footage of campus they had, constantly comparing themselves to empires.
In my experience CXX folks were all about being seen and having something tangible to show off to potential partners and customers. It's one thing to give people a tour of your facility. It's another to meet up at a co-working space and settle in for a PowerPoint presentation full of abstract numbers and graphs about your "virtual "company. I'm not saying that's right, and I'm certainly not arguing for RTO, but it helps explain that motivation and total lack of confidence in WFH.
It's still a "primitive ape-brain" thing to do though.
