The claim of spontaneous order is that if things repeatedly reorganize
and compete among themselves, the resulting order is likely to be
"good" in some sense. States are too long lived; their current
configuration is determined by their initial configuration and
internal politics more than by competition among different states.
For instance, most US citizens haven't considered moving to other
countries, so the US isn't being forced to compete with other
countries to provide a desirable living environment. (Maybe the US is
providing the best living environment, or maybe it isn't; that's not
my point. My point here is that most people born and raised in the US
haven't seriously compared it to other alternatives.)
States are like DOS - a stable standard that is there for historical
reasons, not because anybody would choose it now. After enough time
passes, they'll become less relevant, just as the latest version of
Windows NT can't run all DOS programs and I don't care if Linux can
run all DOS programs. With advancing communications technology, the
evolution of these organizations speeds up, so the state ages faster.
