I worked remotely for years before the pandemic too, so I am not a newbie to remote work who just doesn't get it.
I get value from the office being a good social space, and a good space to focus if I am noticing my self-dicipline drift. There really is some good adhoc discussions that happen in person that just don't occur online as well.
I would never give up WFH though, it is what allows me to handle the whole week in general. Fewer distractions, no commute means more rest, means better thoughts. If I were a perfect worker robot it wouldn't matter where you put me, but I am a human so my needs fluctuate. Having options lets me be where I can work best and be happiest on any given day.
