I see, so your definition of luxury good is "something that can be functionally replaced." I was thinking of the economic definition.
I don't think meat to be functionally replaceable with plant proteins. Heme-iron alone makes it very difficult to do, since iron from plants is far less bioavailable. What does a vegan diet do for Vitamin B12? Conspicuous consumption is not necessary for survival, but B12 very much is.
I don’t notice a day-to-day difference.
Changes from nutrition can take a long time to become manifest. I wish you longevity and good health.
