I don't think that entirely how the economics work.
If you transfer your EUR, USD, whatever to Bitcoin, it would make sense to delay any purchases to next week/month/year, because you would at this point get more value for your Bitcoins. This is bad for any retail that's not sell food or other essentials, where you can't delay the purchase.
When you see government and national bank attempt to pump out money, they are trying to do the opposite. This means that if you want to buy a new TV there's no point in waiting, you won't get a significantly better deal next month.
Bitcoins are still a bit weird, because you currently can't cash in large sums. You can't do your transactions in Bitcoin, you need a stable proxy currency for setting the value of your goods. We have maybe 8000 active products currently, all manually price in five difference currencies to maximize profit. This only works because these currencies are pretty stable and we can avoid adjusting the price for a product after a few month after initial release. It priced in Bitcoin, we would have to adjust the price of every single item multiple time a day. Of cause given the price fluctuation it would still be more profitable to simple buy Bitcoins, rather than physical goods and the later sell them... But that would be bad for employment.
Yeah, I'm not a fan of Bitcoin, precisely for the reason other people like it. I believe that governments need to be able to control currencies. If you don't trust your government, then that's a different problem.
