Social Experiment. Become Me. What I see, you see.
I think that there is some merit on his reasoning, when it comes to the skin fauna and bacteria. However soap is not there just for disinfection, it's also to remove grime, as it makes oily grime soluble. And with or without capitalism, you don't want to be grimy.
Also, the body odour part screams "appeal to nature" from a distance. Sure, we are animals; and sure, we produce body odour naturally. However that does not mean that body odour is desirable.
We haven't always bathed daily, but we've had perfumes for thousands of years. I think that's probably significant as well.
Daily bathing is a fairly new societal invention. We were driving cars and lighting our homes with electricity before we were bathing daily. I wonder how BO was thought of before now, it certainly couldn't have been considered as offensive. Cultural attitudes plus smell adaption? I just couldn't imagine some old west cafeteria during the lunch rush not being unbearably smelly.
This is far from scientific, but I swear I have better "luck" on dates when I don't wear deodorant or cologne. Like, I'm obviously freshly showered so it's not like I smell bad, but maybe there's a subtle chemical communication thing going on? Or maybe I just don't smell like every other douchbag, idk.
We can't sense feromones like other animals apparently. But maybe you have a good body odor.
This article is wrong about collagen supplementation, which is very well studied and does improve skin elasticity and is important for ageing people's skin. https://pubmed.ncbi.nlm.nih.gov/33742704/
I take this person's point RE washing and frequency is something we should reevaluate, but being sweaty after a workout, bathing feels like the right thing to do, soap or no soap.
