> Is the positive impacts anecdotal?

No. Lack of commute is concrete and tangible. Even just from an emissions standpoint.

Decreased spending on office space is not anecdotal, but again concrete.

These are externalities to worker productivity, not necessarily correlates of it.

Sure, if you don't consider worker productivity to be a ratio work per unit cost.

Reduced office costs are real. You would have to pay more per employee just for the office costs alone.

This then demands concrete proof that productivity is higher in office -- which has never been provided.
