I don't like wfh because I don't like being all alone at home all day. But my preference for office hinges upon the presence of other people in office too! That's why I encourage everyone to come to office and work.
Perhaps find a good video chat solution, it's not safe to come to work right now and hopefully you'll find having chat gives you the sense of being with others that you need.
Social interaction in one's free time is a matter of preference - you can stay home alone, or ring up a friend and go for a coffee.
Maybe eventually people can find a group of friends/acquaintances with which they can also hang out and have a coffee, while each tends to their own work?
