Idiotic? How do you think we evolved from Australopithecines two million years ago up to about ten thousand years ago without bread and milk, up to about 150 years ago without toilet roll and toothpaste, and up to 100 years ago without shampoo? They are not essential! Yet our species would have died out long ago without veg, roots, legumes, nuts, fruit, meat, birds and fish. They absolutely are the essentials! I went to my local shop for my cleaning products.
