I think the real thing to keep in mind re: fuzzies and utilons may not be that you should always purchase them separately. (What's wrong with a package deal?)

I thought the article about fuzzies and utilons was essentially a warning that, at least for the author of the article, package deals are strictly worse. Which may be different for different people.

The reasons is that mere checking for utilon-efficiency of the package deal kills some of the fuzzies. By mere checking whether your package deal is utilon-good, you are making it fuzzies-worse. On the other hand, if you don't check it, it could be utilon-worse, and you wouldn't know it.

That's why the recommended solution is to buy a greater thoroughly examined utilon component, and a lesser unexamined fuzzies component separately.
