"You mention the expensive costs dropping with popularity, then when I point out a plate of fried eggs and bacon for breakfast at the diner has always been pretty cheap and nothing new, and they don't "need" GF pancakes or GF toast to serve naturally GF food, you turn it around and make it an availability argument instead..."
The availability issue was part of my original post, as well (viz., my points "b" and "c"). You assumed I was talking about junk food, and I had to elaborate my position in response. That's a clarification, not a topical shift.
For what it's worth, I totally concede your point about produce and meat. To the extent that you believe that such things invalidate my point altogether, well, that's where I needed to add clarity.
