Taste has nothing to do with it; 'tis is all based on economics and the actual way to stop meat consumption is to simply remove big-ag tax subsidies and other externalized costs of production which are not actually realized by the consumer. A burger would cost more than most can afford and the free market would take care of this problem without additional intervention. Unfortunately, we do not have a free market.
So there's no point in pushing for pasture raised, and it's either all or nothing ?
I think incremental progress is possible. I think rolling back and gag laws would make a positive difference in animal welfare because people would be able to film and show how bad conditions are inside.
I think that's worth pushing for. And it's more realistic than everyone stopping eating meat all at once.
The economics of what you describe are impossible. The entire concept of an idyllic pasture is actual industry propaganda which is not based in objective reality.
