I don’t think an international government would be very positive as it is more likely to benefit some more than others, more like a coalition of communities that are willing to stay out of each other’s business but also help and support each other when needed.....Something like the UN but less influences by the interests of nations and more focused on the interests of regular people. We can still have borders and nationality but our humanity can extend beyond them as we do not need our country to be #1, we want all of humanity to rise together.
I don’t suggest a formation of a new organization anytime soon though. As we change our perspective and resources spread, we can focus on our own communities first and build something from the bottom up, then the organizations that can adapt will, the others will shed away naturally.
