Oh I agree, but if attendance is a performance metric then the work going on doesn't need an expensive white collar management infrastructure, which I think is part of Dr Burry's point (even though the article is referencing cooked studies about WFH productivity loss and couching the reference in weasel language).

You seem fairly resolute that knowing if someone has their butt on their seat is useful, but I would invite you to try finding some other metrics that actually measure output, and try rewarding people for performing highly on those metrics. I can tell you, I've seen countless unproductive hours wasted with butts firmly on seats. It's not a good measure of productivity.

What kind of job has no other measurement for output than time spent in a chair?
