It's easy to make a case for WFH when your job is basically "Work alone for 90% of the time hitting keys on a keyboard". Hell there are tech workers who are going on 20 years of remote work. WFH is an old concept in tech, because the work is almost custom tailored for it.
HN is out here hitting softballs in the battle over retrun to work. However, the overwhelming majority of white collar workers are not tech workers, and do jobs that require way more human interaction. This is where the actual strain between workers and employers is.
