In theory, I agree. However, this is only currently true for small parts of the beef supply chain in the US. The vast majority of meat tissue growth people eat here comes from factory farms.
I don't have a major problem with meat eating when it's done sustainably and humanely. The real issue is that this is not the case for way too much of it now, and current meat production practices are yet another example of unsustainable overconsumption in general. Yet more than half the population regularly celebrates and enshrines that overconsumption, reinforcing it. This is not a good look to anyone who's really thinking long term & globally about these things.
Depends on your definition of microscopic. The USA is a world-leading producer of a number of agricultural products, including corn, soybeans, beef, and in the top 10 producers of a staggering number of other crops.
