That is cool and all, but if bitcoin was ever even close to being "mainstream" you can bet your ass there would be a bazillion articles, FB posts, tweets, etc from people who do
not like the idea of being locked out of the economy unless they buy "the future of money" from a relative handful of early adopters. Such an idea is, to be blunt, complete horseshit. The idea that every person on earth needs to first purchase Bitcoin from a handful of early adopters in order to continue to participate in the economy is flat out loony-toon nuts. No matter how Bitcoin evangelists try to frame it, it's just not gonna happen.
Don't think that the lack of discussion about this means it isn't an issue. It is a massive, massive showstopper to Bitcoin adoption. The reason you don't see more people talking about this is because Bitcoin is absolutely nowhere near becoming the default currency used by anybody. Much easier to beat up on all the other massive technical flaws in Bitcoin...
