I have changed my peanut butter choice - when science started realizing trans fat was a problem I switched before the law changed to reflect science. I have also tried various of the 30 different options in other situations and found the one I personally like best. The value isn't just that I can make a choice, it is also that other people really do make different choices.

You are forgetting about the time factor. I don't make a choice every time, but I'm not a 22 year old out on his own for the first time either (22 was about 30 years ago for me, and there are reasonable odds I have another 30 years to go). I don't have to make a choice every time to take advantages of choices.

It’s funny you defend your independence by giving explanations of how you changed your peanut butter buying habits. The point was we don’t care what kind of peanut butter you buy; it’s not a meaningful kind of choice to have.
