I believe rconti was not talking about the duration of COVID19 issues, nor the duration of WFH. Rather, the evolution of economic norms given the assumption of sustained normalization of remote work.
I think you're mistaken, since WFH gained massive adoption due to the COVID-19 outbreak. It's also what I believe he's referring to by, "Yeah, it won't last forever." I don't appreciate the downvote either for a reasonable comment.
