Well, then no country will be able to inflationate the currency by printing loads of money like they do now...
That is true. However, the USA sets a target of a little inflation for the reason that they want to encourage spending and keep the economy moving. With a deflationary currency, as you know, people are more inclined to save since their savings are growing in value.
I am tempering my enthusiasm for bitcoin because I don't know how it will deal with recessions. There is a role for the government in those economic times and bitcoin doesn't provide for that. We shall see, though.
