Don't kid yourself. There is no animal friendly way to produce milk on any economic scale. Even if "organic" farms didn't forcably impregnated the cows (which most of them still do), they still take away the calves and hand them over to the veal industry.
Yes yes there's always a true Scotchman argument to be made about how something isn't 'really' animal friendly, but between being butchered for meat or being milked when living on a pasture, using butter to fatten up artificial meat would be a huge improvement in animal welfare.
