The horror that is factory farming only exists because of profit motives. Remove the profit motive and whole thing comes tumbling down (because it’s just unsustainable).

Nope. The horror of factory farming exists because herding/ranching exists. It's the descendant, the result of the transition from extensive herding (which is also horrible) to intensive herding (which is obviously horrible). The CAFOs are the ones making profits by economies of scale. Most of the animal products are from CAFOs. End those and it's going to get really surprising :)

Profits existed way before, with pastoralism. The "livestock" or "living capital" is a form of primitive accumulation, part of the formation of capitalism. The profit incentive and the GROWTH incentive goes deep in pastoralist culture. The notion that it's in any sense non-profit is absolutely incorrect.
