If someone likes socializing, they can do more of that when WFH too (especially since WFH really means: working from anywhere, be it a cafe, a coworking space, a village, or wherever they like).
Except it their have issues at their home. But going to an office is not a solution to that, is sidestepping their real problem...
The only place where that's not good is when you need expesinve resources to work (e.g. access to labs and machines).
