Maybe this is the pendulum swinging back to in-person fellowship. I remember reading a book years ago called "Bowling Alone" in which the author described the breakdown of our social institutions such as service organizations, churches, local businesses and so on.
My first thought was back to the Kansas City Woodworkers Guild and the open shop there. These sheds appear to be sort of a scaled down version of that.
