I've always thought that the part of my brain that instantly resonated with Bitcoin was the part that grew up in the Argentina of the 1970s to 1990s... we have a leg up when it comes to a deep understanding of money that others, like Americans, are only now coming to terms with.
This has also been my experience. It usually only takes 5 minutes of talking after a Mexican, Argentinian, or Russian 'gets' what the real advantages of Bitcoin are. It's also striking how many bitcointrepreneurs have roots in eastern Europe for example (Romania, Slovenia, Ukrain, Russia) - I don't think this is a coincidence. There is a lot more Bitcoin inertia in Europe and the US.
