Cite your sources. This is a statement made by many without evidence.

Sure, if we all had a cow and two acres and lived in a temperature environment where the animals could graze all year, we could have milk after the cow has had a calf. But who impregnated her? And what are you doing with the calf because it needs two acres of grazing pasture too. And then who impregnates her next year and what do you do with that calf? Another two acres? What about the harsh winter or summer? You're going to need to supplement with extra hay. Off to the agricultural supply who... ah crap, they farm. Farming kills fuzzy animals! Now we're terrible again!

Cows, like all mammals, aren't unending milk supply systems. They dry up because they lactate for a reason. Your imaginary hobby farm is an unsustainable system.
