You make a good point. It's easy for me to criticize Bitcoin from the standpoint of assuming it is the official currency of some country, or the world's only currency.
However, in so doing I am unintentionally ignoring the much more relevant and likely possibility: that Bitcoin doesn't take over the world, but is simply so easy and useful for the cases you described that it "just" becomes the "Internet's currency".
This softens my criticisms of how a deflationary currency carries risks, since in this scenario Bitcoin is continually being converted to and from other currencies.
