Odd that what you call a "luxury industry" is essentially something that poor people have been doing for over a century. I generally agree that trying to eat less meat, especially beef, is a fine idea, but farming, ranching, and BBQ are all industries that are about as far from luxury as you can get.

What is odd is how meat became such a cheap product. The ratio between calories of grains (to feed the cow) to calories of meat is what, 10:1? It is a luxury item. Humans started consuming it in large amounts only in the last 50-100 years.
In general, I feel like you're conflating "modern" with "luxury" in a way that doesn't feel reasonable. Just because we haven't being doing something for long, or that it requires effort/inefficiencies doesn't mean it's innately "luxurious". Certainly not everything modern is good, but almost everything about food even in non-western countries is calorie inefficient and relatively modern as we invented new ways to cook and farm, and spices and cooking methods became more diverse.
