Basically all centralization of political power in human history has been accomplished by force. See Rome, Persia, Germany, USSR, etc. etc. etc. Even the USA's transition from a union of united States to The United States occurred under force of arms. Sadly, this centralization of political power has been a disaster for mankind IMO. Even as we've transitioned from monarchies to democracies over the last few centuries, the trend has largely resulted in the replacement of actual, determinative choices with merely having a millionth of a share of a choice. Not a determinative choice, but a say. Consider the holy roman empire, for example. [0] Under this scheme of decentralization, people had an actual choice of their government. Say you were a merchant in Mühlhausen circa 1700, and you found yourself in opposition to your local government. You could simply move a short distance to a different area and be beholdened to an entirely different government. You'd have 50 choices within 100 miles! While it's true that the HRE was all under the administration of one government, but it was extremely weak. It lacked, for example, the ability to levy direct taxes. After unification in 1870, the same merchant would've had to move much further to escape his government, and his options had been diminished by 95%. After European unification, he would have to travel to another continent! While democracy has given us control of our governments in theory, in practice the "choice" it offers is much less empowering than the determinative choice afforded by decentralization. The larger our political entities grow, the more diluted our "say" and the fewer full choices are available to us. In the United States, we have less than 1/100,000,000th of a share of the choice in our chief executive! While democracy is obviously preferable to Aristocracy/Monarchy/Tyranny, on it's own it is still only a marginal improvement. At worst, you can still end up with 49.9% of people living under a government they oppose. Decentralization solves this lingering problem, because it allows people to self-sort in and out of countries they don't like, allowing for people who truly despise their governments to choose themselves a new government. In the absence of such a safety valve, people are forced into a zero-sum struggle for power. It is rule or be ruled. Dominate or be dominated. We're seeing this in the United States right now. We're not at each other's throats because we hate each other. Not even because we hate each other's politics in the abstract. We're at each other's throats because neither side is content to be ruled by the other. The same reason that centralized entities only arise by force is the same reason they fall apart in the end. People don't want them. They don't want to be dominated. Centralization of political power forces people into an inescapable struggle for power. It is the enemy of peace and tranquility, and a blight on humanity. [0] https://commons.wikimedia.org/wiki/File:Droysens-26.jpg https://commons.wikimedia.org/wiki/File:Droysens-26.jpg
