Do you still continue to use USD/Euros/other national currencies for over 90% of your purchases in value terms? If yes, then I guess the central bank is not inflating the currency (otherwise premise 1 is wrong). I'd be interested to hear you confirm that. If no, then please tell me what you do. I'd be even more interested to hear about that.
If this reasoning applies to you, why wouldn't it apply to others in a similar predicament?
If no, then what do you use?
Of course we are still using euros & dollars, because up to now, no other currency could overcome the bootstrapping problem of network effects, to be useful. Bitcoin is changing that. Thats why we are all here, on the bitcoin forum.
Why are you on a bitcoin forum? Just to pester and annoy people, it seems.
