The productivity estimate from focus is off, especially for employees who do more than solve immediate, light problems (you were already taken to task for essentially claiming there is no such thing as a highly productive employee.) The additional cost also isn’t typical everywhere. Going by your math, you should be recommending full offices in much of the country.

Finally would note you don’t have a monopoly on executive perspective in this thread. It’s to the credit of others that they can understand why they perhaps should eschew a traditional visual indicator of power disparity that would favor them.
