This article is from 1993 and makes a strong case that secession and smaller political units are freer and more compatible with trade, production, and capitalism. From Hans-Hermann Hoppe at lewrockwell.com:

With the collapse of communism all across Eastern Europe, secessionist movements are mushrooming. There are now more than a dozen independent states on the territory of the former Soviet Union, and many of its more than 100 different ethnic, religious, and linguistic groups are striving to gain independence. Yugoslavia has dissolved into various national components. Slovenia, Croatia, Serbia, and Bosnia now exist as independent states. The Czechs and the Slovaks have split and formed independent countries. There are Germans in Poland, Hungarians in Slovakia, Hungarians, Macedonians, and Albanians in Serbia, Germans and Hungarians in Romania, and Turks and Macedonians in Bulgaria who all desire independence. The events of Eastern Europe have also given new strength to secessionist movements in Western Europe: to the Scots and Irish in Great Britain, the Basques and Catalonians in Spain, the Flemish in Belgium, and the South Tyrolians and the Lega Nord in Italy.
From a global perspective, however, mankind has moved closer than ever before to the establishment of a world government. Even before the dissolution of the Soviet Union, the United States had attained hegemonical status over Western Europe (most notably over West Germany) and the Pacific rim countries (most notably over Japan)—as indicated by the presence of American troops and military bases, by the NATO and SEATO pacts, by the role of the American dollar as the ultimate international reserve currency and of the U.S. Federal Reserve System as the “lender” or “liquidity provider” of last resort for the entire Western banking system, and by institutions such as the International Monetary Fund (IMF) and the World Bank. Moreover, under American hegemony the political integration of Western Europe has steadily advanced. With the establishment of a European Central Bank and a European Currency Unit (ECU), the European Community will be complete before the turn of the century. In the absence of the Soviet Empire and its military threat, the United States has emerged as the world’s sole and undisputed military superpower.
