At this point, if he is Satoshi, he would probably be better off coming out of the closet. If you read through the McGrath-Nichols documents about the Hotwire bankruptcy and how the R&D tax credits dispute killed Hotwire, it's clear the ATO has it out for Wright.

I bet that whatever this raid is about, it's about something like R&D tax credits again (http://www.businessinsider.com.au/the-australian-who-may-hav... says $54 million in 2015 alone!) or some sort of VAT rebate, and it may kill another of Wright's companies. There's not much you can do against the ATO if they are determined to reach an adverse decision against you... But if he's Satoshi, he can take the moral high ground and wage a media campaign to shame the ATO into dropping the case and maybe finally correctly treating Bitcoin as money.
