Don't you literally make sourdough starter out of thin air? Why would you get it from somewhere in the age of social distancing? I would have assumed that the answer is people are leaving flour and water out (and I'm sort of thinking of doing so, myself), so I'm surprised that the conclusion of this article is that they're actually getting it from somewhere. My goal isn't to make the tastiest sourdough, my goal is to have bread at home without leaving the house. (And I don't have any yeast.)
