Thank you - this is the most sensible comment I've seen in this thread.

Many thinkers throughout history have noted that states and criminal gangs are effectively the same. They are both inherently violent organisations. Criminal gangs are tiny states; states are large, settled criminal gangs.

The Yakuza in Japan or the Cray family (when they ruled half of London) are examples of intermediate forms: criminal gangs that have taken on some of the role of the state. Rather than arbitrarily robbing people, they instead ask for protection money. This is more than just a polite form of robbery: they legitimately protect you from other criminal gangs. Though I doubt anyone here has had to make the decision, I think everyone would prefer to deal with one predictable criminal gang than many competing unpredictable gangs.

Eventually the gang leaders realise that it's in their own interest to build a stable, prosperous society: its better to be a Caesar than a barbarian warlord. If nothing else, the wine is nicer. Passing laws and promising that even the leaders will abide by them makes the citizens comfortable dealing with one another and makes everyone richer. Once everyone is comfortable with the idea of the law being supreme, the mob might realise they can do away with kings and bring in constitutions and parliaments and so on. Democracy works (and only works) because the mob agrees that these are the set of rules they will live by, and that therefore it's not wise to ignore them.

Still, rights and laws remain contingent on power. Human rights only extend as far as the military reach of states that support human rights. Until we build a world government, the only universal law over humanity is the same as it was in 10000 BC: raw power, physical force, violence. The world as a whole is essentially a lawless realm consisting of about 200 gangs; the only thing that stops everything turning into bloods vs crips is a shaky system of alliances, treaties and, ultimately, mutually assured destruction.

One obvious counterpoint is that France no longer needs to fear Germany because the Germans and French are suddenly BFFs and neither will vote to go to war with the other. The "international community" is slowly coming to resemble a federated state, with one set of laws. But this community is not truly international. Russia and China can violate your right to privacy all they want. Ultimately, this is because they have H-bombs. Likewise, we can violate Sharia Law as much as we like and Iran can't stop us.

My point is this: most of these complaints would make sense if America truly was a world government, achieving legitimacy via just consent of the 7 billion governed. But it's not, and it can limit its citizenship however it pleases. The fact that America was historically built on immigration doesn't give me, a foreigner, the "right" to live there. The very concept is nonsensical - the USG has more guns than me, and so they can decide who's in and who's out. The idea that people should be able to live wherever they want is a beautiful dream but is entirely counter to the way the world is going, and is also horrendously impractical.

I've travelled to China a few times over the last few years and each time the visa requirements have gotten stricter. They've decided they don't need any more foreigners, and I can't contest the morality of this with the CPC because again, they have more guns than me. As the world gets more crowded, other middle income countries will follow suit. The walls are going up everywhere. As much as I, personally, would benefit from the US tearing down its borders and letting me live there without restriction, it doesn't make a lot of sense if they do so and other countries don't.

Americans can constrain their intelligence agencies and open their borders as much as they like. They can't force other countries to do the same, which means that these policy proposals are equivalent to "we should make our intelligence gathering less capable than that of China and Russia" and "we should import Latin Americans until our quality of life is equal to that of Honduras". If America wants to reenact the fall of Rome, that's their prerogative, but as a foreigner I wish other foreigners would not cheerlead them as they do so. No America means no "international community" (what can the EU do against China and Russia?), and good luck petitioning China to respect your human rights as a global citizen.

Although you might not believe it, I'm not actually a cynic about human nature or pessimistic about our future. We built stable, peaceful societies in a violent world. Go humanity! But we have to remember that this was not achieved by the divine intervention of the Great God Human Rights, but by working within the universal laws of power. Good can triumph over evil, but as even Jesus said, it needs the "cunning of snakes" to succeed.
