I agree with you that this concept is useful for explaining ideologies to people and giving a quick rundown on the major ideologies vying for control in the world. This is an insightful comment and well thought out.
I think it is possible to live in a world with nationalists and not have war or extreme stratification of wealth and resources. I think it is also possible to live under a global government without a handful of psychopaths running the show from the top.
The only reason we are presented with such limited choices is because the most wealthy and influential people on the planet right now are trying to make it that way. All we have to do is adopt more and more decentralized platforms until eventually the power is stripped away from the few and put into the hands of the many.
The population can then decide for themselves, with a TRUE equal-weight voting system, what form of government they want, whether it be global or nation-state, and all nations can cooperate with one another for the benefit of the collective instead of utilizing third world countries as sources of cheap labor or oppressing their citizenry.
