Yeah, one of the things to remember is at any scale, to get more milk the mother must be impregnated. And her babies drinking that milk (which is why it was produced) would take away from the profits of selling it, so they will separate the babies from the mothers so as to get as much milk as possible, and then repeat this. Once the cow cannot produce milk anymore/isn't profitable, the cow ends up getting killed for meat, sometimes leather, etc. It's awful. And even small farms' goal is to make money, the local small farms near me all do this (having visited most of them).

And not to mention all of this views animals as commodities.
