I don't see how them imitating 8 hour work a day in say 2 actual hours is any improvement.

You immediately assume people don't work which is not what I am seeing. Sure, some absolutely do, but you are making it look like everyone is more lazy in WFH conditions.

I don't assume anything, just going by with your hypothetical 8-hour slacker.

My bad then, but I still disagree that hours put are an objective metric. Yeah, sure, 8h have passed <- this can be measured objectively, but it's basically the only thing that can be measured objectively in a work setting.
