These are things that can never be replaced with WFH and shouldn't need to be. It's not a problem right now since we're all WFH as we're in the middle of this pandemic. Once we return to safer times, some of us will really want to stay WFH, but they'll begin to miss out on a lot of these small interactions. People won't realize they missed out, and it'll never be intentional, but it'll happen. At some point it'll become a forcing function to bring everyone back into the office.
I am definitely pro-WFH a couple days a week, like Tue/Thur or Wed/Fri. Make those meeting-less days and I can use those to go into deep focus mode. If the whole company does it then we won't miss out on any in-office banter.
This isn't to say there aren't roles that work well fully remote if the entire team is fully remote too. Keep in mind those are going to be less-creative projects and much more task based, and if that appeals to you, those will always exist. They existed before the pandemic, and what's different now is that these types of teams can now flourish in bigger companies as well.
