Humans are mammals, like cows, so biologically we share a great deal in common, including the production of milk for our young. It doesn't make sense to argue against consuming something on the basis of "what it was intended for". Nature makes no such distinctions when it comes to acquisition of energy. Fruits and vegetables are not "intended for human consumption" either, they're intended to spread the plant's seed away from other competing plants. Cooked cow muscle fibers, also known as steak or beef, are intended for movement, but they are also delicious and nutritious. Organs of ruminants and birds, such as liver, are also extremely healthy for humans to consume, but they of course were evolved with other purposes in mind. As for "big milk", well milk is an extremely dynamic food used to produce a large variety of delicious products like cheese, butter, cream, yogurt, whey protein, cake, milk chocolate, etc. Milk consumption also pre-dates modern advertising by 9000 years or so, with earliest signs of human cultivation of milk from cows dating back to the Neolithic. And to the extent that you choose some milk alternative over milk itself, are you just falling for the Big Almond or Big Soy industry's alternative propaganda?
