But this is not lack of choice. It's lack of availability. Wouldn't one good brand of pasta solve most of your pasta needs? Do you really feel like you'd still be unhappy unless you had 10 shapes of pasta each made from one of three different grains, each available from two or three different brands?
The fact that I don't eat fusilli very much doesn't mean that other people don't.
The thought experiment surrounding the removal of choice is not the removal of choices that other people make. It's the removal of your favorite choices, particularly if you are a minority.
