I don't think this is much of an insight, to be honest. The "anthropic" interpretation is a statement that the universe requires self-consistency. Which is, let's say, not surprising.
The purpose of natural selection, fine-tuning of physical constants in our universe, and of countless other detailed coincidences (1) was to create me. (Or, for the readers of this comment, to create you)
My feeling is that this is a statement about the English language. This is not a statement about the universe.
