Here is why I cannot see bitcoin becoming a "currency" - lack of a central authority which can enforce stability on its value.

If a loaf of bread is going to cost 1 milli-btc today and 2 milli-btc tomorrow, that will simply wreak havoc in the society. Most folks just want a stable predictable life with as little volatility as possible.

Say what you want about modern central bankers, they have kept things mostly stable. 2008 crash was the worst thing happened on their watch, which is mild in comparison to other horrors of the past (like great depression).
