The McDonald's analogy is pretty good since you can also go to any other fast food joint or even cook for yourself more cheaply and nutritiously than you eat McDonald's. People have sentimental feelings about McDonald's, prefer the style of fries, etc. - it isn't that McDonald's products are incomparable or irreplaceable and that the only alternative is expensive, difficult "gourmet" food.
