I always thought Satoshi Nakamoto was an anagram.
Antonomasias ~ Satoshi Nakamoto
Antonomasias: the substitution of an epithet or title for a proper name (e.g., the Bard for Shakespeare).
So it seems like a play on words, because Satoshi Nakamoto is a real name, and therefore a group might have wanted the creator to have a human name.
