Theoretically it should be way less energy intensive as well, since there won't be an animal expending energy to live for months before slaughter. Nor will there be a need to grow feathers, bones, or blood that end up as byproducts. Of course, this tech is still being developed, so it probably hasn't reached optimal efficiency, but it doesn't have to be that efficient to be better than standard animal agriculture.

Well, if the cow eats grass, then you aren't paying for that energy input.

It's not the input. It's the output. Stock animals emit gasses (like any other animal) and it's non-neglectable footprint.

"Grass-fed" doesn't scale to the meat demand. It's a complacent luxury for some people, and that's all it's ever going to be until the Human population at least halves or becomes mostly vegan (so some people can enjoy better meat).
