You think XYZ Company is going to listen to some consultant telling them in a press release that they should go back into the office because some REIT needs more money in it? Why would the CEO of a tech company care at all what the value of their leased office building is? Do you understand how leases and real estate works?
I understand there's significant motivation behind the potential of losing $800 billion in value.
I think those kinds of numbers can have more fundamental implications.
