This is just not true, or at least extremely US-centric. In large parts of the world most meat consumed by the public still comes from small to medium farms and family agriculture. The globalized neoliberal agro-industrial complex has been whittling away at that, but it's still true in a lot of places, and it could be made true again in the US; the population density of the US is pretty low, there's a lot of land on which family farmers could produce meat humanely and sustainably. The only reason it doesn't happen is because agro-industry doesn't allow it, and they have captured the regulatory framework in their favor. If you changed the regulatory framework in a way that penalizes (or downright prohibits) a lot of these horrendous industrial practices sufficiently, then sustainable and human agriculture absolutely could fill the demand even of the very carnivorous American public (at somewhat higher prices, but not more than say double the price.) I'm not saying we shouldn't reduce mean consumption, just that the argument that sustainable and humane methods couldn't meet the demand are BS.
