A world government creates an absolutely massive potential for global despotism, and makes rebelling against an unjust government extremely difficult. As for small city states, that's essentially taking humanity back several millenia to when small groups of people fought with other small groups of people for dominance. Some would win, dominate, become larger, subjugate others, its been done. With small city states, you would not have the scale needed for the development of modern medical technology. We would likely live in a pre-industrial revolution society. There would be no video games or computers or smartphones. There would be potatoes.TheMagicLemur said:Which is why nationalism is awful. I prefer the idea of either a unified world government or small city-states. the nation-state is an awful, awful concept.tehpiemaker said:Every single country has done something wrong. Just about every country and culture has killed, enslaved and harmed others. We are a very young and recent nation. We didn't have time to do things slowly if we wanted to stay caught up with the others. We had to make every decision quickly and that means our mistakes happened more often. Compared to other Countries we are like a teenager stuck in power while all the other older and (Honestly) less powerful countries look down on us saying we have little experience and knowledge (which may be true) of what the world needs.
Atrocities have been committed in the name of the nation-state, but with the nation-state there would be far more conflict. Have you ever heard of the "balance of power?" It also applies to the climate (off-topic) but it is essentially what prevents chaos. If the powerful forces in the world are kept in check by not being too much more powerful than one another (It was a pre-20th century European concept) conflict will be kept to a minimum. Nowadays, we have fought, millions have died, so that we can all see the dire consequences of war and realise that peace is much better than war. That would not have occurred without the nation-state. Would you roll all that progress towards peace back just to satisfy utopian idealism? Would you make the 65 million deaths of the Second World War be in vain? The Cold War made conflict even less likely because of the Mutually Assured Destruction. To those who wish for fantasy worlds, that's a bad thing. However, for those who enjoy living in peace and not having to worry about being sent overseas to die it is very much a good thing.
You're talking about implementing things which would require a complete overhaul of human nature. Don't blame the nation-state for all the wicked things about the primal parts of human nature. Instead blame the individual human who choose their more primal side. I see you at least understand the need for government, but you go to two extremes, very small government and very large government. Neither is best for humanity. Let's go with what we have, and try to make it work as best as possible.
