I think a lot of this boils down to extroverts' dependence on external stimuli, especially human interaction, to make them happy and feel self-fulfilled. While not exclusive by any means, it's extroverts who naturally seek and--arguably--who are good at starting and running businesses. So, there is a bias toward those who are making the call for a return to office--execs--being extroverted by nature. They are confusing consciously or subconsciously the drivers for why workers should return to the office being arguments around productivity rather than their needs and biases.
