I've worked primarily remote since 2016; but I have the option of going to an office a few miles away when I want to. My wife, forced to work from home, finds the entire experience to be socially isolating and misery inducing.
> work from our own comfy homes instead of rolling into a crowded, stuffy office everyday?
This one-sidedness is a strawman. Not everyone's home is comfy or has space for working; some people made housing decisions based on one person leaving the home for most of every day (e.g. choosing a smaller apartment closer to city). Not every office is crowded and stuffy; some are quite pleasant. Not every worker gets their social needs met outside of work, and forcing them home ends up isolating them from the primary source of social interaction in their world, with all of the mental health and well-being issues that entails.
Personally, think that "more remote work" is the way to go, but the issue is more nuanced than "why are people resisting this obviously beneficial change?"
