>as you come in contact with other people, you eat dirt, you hang around farm animals, etc, these are all mother nature's way of helping you develop that microbiome

I find that way of personifying our environment counter productive. It's not mother nature's way of helping us, it's that we evolved over millions of years in this environment and to change that is to hinder ourselves. I find this a much more accurate and convincing way of arguing for a back to nature style of development and nutrition.
