It’s survival. The English have water fountains in their bathrooms to rinse off the anal region, then wipe off. It’s essential the same thing, but with a reusable towel that you would clean.
Animals after defecating clean their anal region with their tongue, so they use it as a rag. What do you think we did before the commercial creation of tissue? How do you think people cleansed themselves before modern or conventional times?
We’ve become overly dependent and lazy. Why waste money on something that can’t be recycled, when that money can be saved for food or something that is more imperative?
