The whole point of Bitcoin is to be a payment system beyond governments' control. I would be very surprised if Satoshi was spending his precious time contemplating on how governments could profit from it.
If he was really known, I am sure that he would have explained to government how he has factored them in, but I think the thing is left for them now to figure out. One of the reasons why government is still about skeptical about cryptocurrency of bitcoin is that they think that the system will be against them in the aspect of tax because they way that people have portrayed it, like a system they will use to hide from government meanwhile that is not the case.
Satoshi is human and I am sure he understands how government is being run, so he would really not do anything that much to affect government, just the banking sector that I am sure that he is after, because this system would affect more of the banking sectors.
