Bitrustica should be funded by the people for the people.
Bitrusticans rights / duties have not yet been defined. in fact bitrustica is just a wacky idea this point.
The basic idea of bitrustica would be to give everyone in the community a change to vote on bitcoin related issues.
ex.
 It could be in a few years their will be many different bitcoin clients. So who's to say what is the official client? bitrusticans could vote on this kind of thing.
 In time it might be necessary to elect a official representative of bitrustica. right now people might thing B Wagner is the bitcoin community's representative (is that what we want?)

Maybe having a real sovereign country, backing bitcoin could have illegal and/or social benefits that we can't see yet?
