Not just inconvenient, but expensive and out of reach.

Not really. That's exactly when I had in mind when I said "vast majority of people". The biggest problem is access to a cooking fire and some sort of refrigeration you can rely on for most of the year.

It does require spending a little time cooking and probably to shop around rather than getting everything from a (possibly overpriced) supermarket depending on how much you can spend. So it's strictly an inconvenience, it requires stretching the argument really thin to view it otherwise.
