The abstract of the article says that folks who have remote work are more socially isolated, even after work hours.
Maybe WFH allows folks to be more social with the people they want, but the abstract says that they socialise less overall, and are more socially isolated.
Most people live with a spouse , kids, room mates though, I live with my family and they are generally around so get plenty of company (too much sometimes). This is about living alone AND WFH, then yes might be good to go to the office.
