I totally agree. But Satoshi's technology challenges financial institutions, and I believe they employ the same, if not more, resources to track him as they do to catch criminals. In any case, this story is fascinating.
They won't be able to track him because he hasn't left any trace of his doings. Anyone who's a cypherpunk knows how to doing getting caught and such a person would try each privacy enhancing mechanism to avoid others eyes.
He was truly a genius and that's why I don't think that anyone despite spending millions of dollars will be able to know his true identity. Even many cyber criminals who did wrong are still not caught, those aren't cyperpunks but Satoshi was, so now you should think on it yourself to see the whole picture.
