The point is that burritos are not monads. Metaphors are things you see in literature. A key feature that makes them attractive in literature is that they are subjective and can be read in multiple ways. That is the very thing that makes them a poor device to use in technical writing. We do use analogies a fair amount in technical writing, but even those need a careful author to make sure they are made clearly. The core idea of an abstraction is that it is a generalization of something you want to do a lot of. It makes a lot of sense to go over a bunch of examples and explain how they are all the same thing.
