Bitcoin is attractive to libertarians.
.... because of the inherent design principles of the protocol.
Why didn't Satoshi discuss the value of the bitcoin framework to socialists, communists, representative governments? Why did he only mention libertarianism and show extreme distrust with governments?
"Yes, [we will not find a solution to political problems in cryptography,] but we can win a major battle in the arms race and gain a new territory of freedom for several years. Governments are good at cutting off the heads of a centrally controlled networks like Napster, but pure P2P networks like Gnutella and Tor seem to be holding their own." - Satoshi Nakamoto
“We don’t want to lead with 'anonymous.' I am definitely not making any such taunt or assertion [that] 'The developers expect that this will result in a stable-with-respect-to-energy currency outside the reach of any government.'"- Satoshi Nakamoto
Wanting fair money or wanting to invent a revolutionary currency is enough on it's own and doesn't imply any specific political agenda. You can still be a socialist, communist, or believe in representative government and see the value in Bitcoin. It's not exclusive. I think everyone distrusts most modern governments regardless of what political ideology you believe in.
Even a hardcore Marxist would agree with Satoshi's statements that you quoted. All his quotes are simply stating facts. And if you read into them more he's clearly trying to avoid identifying Bitcoin with any one particular political ideology.
He might have been a libertarian. He probably was. But he definitely took care
not to bog down his project with unnecessary political association.
