The mechanism is somewhat dubious imho - why would dirt selectively have beneficial bacteria that other environments don’t? I could come up with some just-so stories about how more “virulent” (haha) bacteria are the only ones to conquer our more sterile world but it’s just a plausible tale.
I do subscribe to it myself but not out of evidence. It’s just vibes. Built my daughter a little dirt box with grass and edible herbs so when she would muck around at five to six months she could do it in there on the balcony of our San Francisco apartment and she enjoyed destroying the plants so at the worst she got some fun out of it.
