Alcohol is still extremely toxic to humans and provides no benefit nutritionally or energetically to our body as far as I know. It's a poor example in my opinion. Millenia of drinking alcoholic products and we can at most tolerate around 200-250ml of alcohol in a short period (for 180lb males). A standard 12 fl oz (355ml) drink's worth of ethanol (about 23 standard drinks worth if I did my math right) would certainly kill anyone.
Meanwhile, I can drink half a gallon of milk in an hour if I wanted to with no real harm.
Other than that, I would agree with your concluding sentence.
