I heard a theory that he claimed a whole bunch of tax credits from the Australian Tax Office which were only possible if he actually owned a large amount of bitcoins (an amount that only Satoshi can possibly own). Now that he's being investigated by the ATO, he needs to somehow convince them that he owns those bitcoins.
