It's not that far-fetched.
Generic bar-soap can be very acerbic and lead to excessive dryness of the skin if used too frequently.
Our skin produces natural oils to keep it soft and healthy but a full day usually covers that layer with dust and dirt.
The solution, then, isn't to stop using soap completely, but finding a soap that has a lower-pH and is more balanced to clean without leeching off your natural defenses.
Because, unlike this pretty boy you claim to dislike but keep subtly praising
, the majority of us adults develop a strong and unpleasant and body-odor after a couple of days sans soap.
