At the rate at which governments are printing money, there should not be a problem buying any derivative and even bitcoins. People will just buy smaller quantities as the price goes up. A full bitcoin might be beyond the reach of millions of people now, but in some years from now, owning a single Satoshi might be a big accomplishment.
We might even see Satoshi's being subdivided into smaller units, who knows. ^smile^
But there is no point to printed so much money and buy any derivative, especially bitcoin which is impossible, I mean, government won't do that and bitcoiners won't let that happen. This is one of the best benefits of bitcoin,
all the money in the world won't be enough to purchase what people are willing to sell their bitcoins for. Not because the money is not enough, but because there are other priorities to be purchased.
When bitcoin reach an amazing price, I hope it's because bitcoin being used as a currency instead of trading object.
