What's the reason for raiding his private space? They're looking for more bitcoins to sell?
Even if he's Satoshi (Which I highly doubt), they have no right to invade into his house. He did nothing wrong.
The police refused to give a reason for the raid on his rented house, but said to ask the Australian Tax Office. He had a giant computer system there that he installed a three-phase power system for, so it must be a monster. The police who raided his office wore shirts with "Computer Forensics" on them, so they were after the computer equipment data
I'm only guessing, but Bitcoins are subject to capital gains tax in Australia, and if he didn't declare them all the Australian Tax Office could instigate a raid. In some countries the tax man can have more power than the police in cases involving millions. Before the police raid they usually knock on the door, the tax man just orders it broken down.

A reporter who approached an office listed as the location of two of Wright's registered businesses, DeMorgan Ltd and Panopticrypt Pty Ltd, in another Sydney suburb, was turned away by police with one officer saying: "There's an operation going on at the moment, I can't answer any questions." Several police officers could be seen speaking with workers inside
The Australian Federal Police (AFP) said in a statement that the officers' "presence at Mr. Wright's property is not associated with the media reporting overnight about bitcoins".
The AFP referred all inquiries about the raids to the Australian Tax Office, which said it could not comment on "any individual's or entity's tax affairs" due to legal confidentiality.
At Wright's rented home, a modest brick house in the leafy middle class suburb of Gordon, three police workers wearing white gloves could be seen searching the garage, which contained gym equipment.
A man who identified himself as the owner of the house, Garry Hayres, told Reuters that Wright and his family had lived there for a year, and were due to move out on Dec. 22 to move to Britain.
Hayres said that Wright had a "substantial computer system set-up" and had attached a "three-phase" power system to the back of the house for extra power.
Police personnel at Wright's office in nearby Ryde wore shirts tagged "Computer Forensics".
