afaik Satoshi went "dark" when government reached out to Gavin for questioning. And since creating any form of money by a citizen is prohibited, it doesn't surprise me he did just that.
I find this somewhat weird:
1. Creating any form of money by citizen ends the citizen up in jail.
2. Developing said 1 further does not end up citizen in jail ?
Too funny.
Could be a trap for him though:
1. Legalize bitcoin.
2. Wait till he spends coin.
3. Then say it was all a big fat joke/lie to trap him ! =D
