The person GP is responding to made it clear they’re willing to pay a premium for a burger that isn’t based on a pyramid of misery, which makes the response all the more misplaced.

There are models of agriculture that achieve better sustainability by using a small number of livestock as unskilled labor to emulate the wild environments that the plants our gene stock come from were adapted to. This will likely be the model moving forward, especially as petrochemical fertilizers get more expensive.

“Just enough” livestock will still get too old to breed or provide labor. They will still have too many babies in good weather and need to be culled in subsequent bad years. That doesn’t put T-bone steaks on everybody’s plate, but it does provide enough animal protein to approximate the traditional Asian diet of a few ounces of animal protein per day, as soup stock and a bit of variety.

The future will still have chicken soup even if burger joints go away.
