Micro nations are not new, and they are almost never successful [1].<p>They are ripe for fraud: selling passports, fraudulent government bank, etc.
In the event that they pick up any traction, they are swallowed by their neighbors with real armies (eg. Minerva), and the rest of the world sighs with relief.<p>An interesting example of one that is still officially around, also claims land in Croatia, and exists just for fraud is the Dominion of Melchizedek [2].<p>Even Lichtenstein, which thrives on laws that allow outside companies to evade their local taxes, skirts on the definitions of "legal", "nation", et al. (though I have a few friends from there who are all great guys)<p>[1] <a href="http://en.wikipedia.org/wiki/Micronation" rel="nofollow">http://en.wikipedia.org/wiki/Micronation</a>
