Here's the thing:
no matter what you do, if you give up the accepted standards of soap and shampoos, and resort to some hippy/tree-hugging approach of less soaps, less water, less frequent cleansing in general, or something to that effect - you will piss off all of us! And deserve every ounce of ridicule you may get. And also deserve to be tossed off bridges, barges, boats, sidewalks... into rivers, lakes, creeks, ponds, especially large puddles... until your beloved nature removes enough of herself and her stink from your dirty self as to not scare off any normal human in your vicinity and/or offend our delicate sensory organs!
Honestly, if practiced correctly, it may make for a more healthy self. You may contribute to a better oil balance, end up less likely suffering swings of extreme dry skin, weak hair, etc... but you will, no doubt, reek to a degree previously reserved for wet and mangy feral humans, or any animal for that matter.
Our natural products, and natural sweat gland production, are most efficient and best for us with only minimal cleansing, best achieved by, naturally, jumping into a body of water and possibly using some kind of scrubbing motion or vigorous rinse-cycle approach while moving about water in either relaxation or hunting/escaping. Soaps and everything are, if you handle yourself appropriately, rather unnecessary to remain healthy.
That is not to say that should ever be the case today. As has been mentioned, we are a social animal, and we surround ourselves with other members of our species routinely.
We don't want to smell each other, we go to great lengths to mask our smells and/or remove our smells, and expect the same from others.
If we can get an entire local group/civilization to commit to minimal cleansing, and surrounded ourselves with like-minded individuals for eternity, we'd never notice the difference after some time, and may become oddly attracted to someone who just happened to, somehow, scrub themselves clean going about their water-based activities.
Ask anyone in the military - a bunch of guys who are around each other non stop, and may be forced to not bathe/rarely change out clothes for a week or longer, may at first notice a little bit of stank - but eventually it's something in that background that we stop noticing.
We adapt to the routine smells and, essentially, stop smelling them. Hell, even if every single human on Earth cleaned themselves daily, using the strongest soaps available, we'd still carry an odor noticeable by anyone not of the same group (any animal, or even a hermit who has ignored all of mankind for the past year). We stink even when we are clean, just none of us really have the ability to notice that base human smell anymore. Any animal can detect our presence pretty damn easily though by smell alone.
So with that said, since 99.9% of the time you will likely be around some human who is NOT practicing your approach to cleanliness, please give up your hippie approach and return to the land of normal. Our noses will surely thank you for it!
