Satoshi new alt-coins would draw attention away from bitcoin, especially government attention. Because of alt-coins, bitcoin grew without much government interference. Good call SN. I do not think that Satoshi used altcoins like Namecoin to draw attention away from Bitcoin. The CIA knew about Bitcoin in early 2011 and wanted Gavin to give them further inside on the topic. So, even if it was his purpose which I highly doubt then it failed. But remarkable is that Satoshi left the whole Bitcoin scene including this forum close after he heard about the meeting with Gavin and the CIA.
