Hayek is NOT one of the reasons we're in this. He has been largely ignored as an economist, unless one makes the assumption that Satoshi was influenced by Hayek's "The Denationalization of Money".
As a political theorist he has had a fair amount of impact with the "Road to Serfdom", which he worked on after Keynes was mysteriously elevated to Sainthood after his death and Hayek largely ended his pure economics writing. There's a great interview with Hayek where he bemoans his lack of impact: https://www.youtube.com/watch?v=Oqhe4K1Jz-8
