Forking is totally possible for states. Different factions are constantly vying for power and many revolutions are quiet shifts that occur behind the scenes. This is very true in complex democratic republics but is even still true in monarchies and dictatorships. Monarchs have power by consent of a whole hierarchy of people and they are subject to overthrow or silent sidelining.
Gold is still the closest thing to a true non-fiat money but even gold has a value based on a consensus and any monetary form of gold will typically come as some kind of coinage for convenience and quick assessment. You can't eat gold.
Money is a social construct.
You could argue that crypto currency promises a form of fiat that is more transparent, auditable, accurate, and open in general but IMHO that remains to be seen in practice. The shitshow that is most exchanges and the majority of flimsy ICOs is not encouraging. All economic systems have corruption and dumb sheep like speculation but this is ridiculous.
