I'm assuming you are ok with an association with cypherpunks / crypto-anarchy, because one certainly exists even if newcomers would rather relegate these roots to history. Hal Finney was a cypherpunk and bitcoin wouldn't be possible without his RPOW system. Wei Dai, who was cited in the original bitcoin whitepaper, was also a cypherpunk, and praised Tim May's crypto-anarchist manifesto. The list goes on...
Cypherpunk is not the same thing as libertarianism or anarchism. I'm well aware that bitcoin has cypherpunk origins.
Too bad that you don't like libertarianism, because Satoshi Nakamoto (you might have heard of him) expressed all kinds of libertarian and anarcho-capitalist ideas.
We don't know that Satoshi was a libertarian, or an anarco-capitalist. Chances are, he wasn't (isn't).
You don't have any evidence about that. And like I said, he expressed all kinds of libertarian ideas, so chances are he is.
There is no such thing as a "libertarian ideas." Libertarianism is a specific movement, not a specific ideology.
