Work for justice. Work for liberty. Work for empowerment of the people. But be smart about it. Abolishing national borders will not get you there. It would turn the world into one big frontier in which various cultural groups would essentially start all over, each seizing territory in the hope that its people might live in peace.
I also envision a world without borders (in a sense). There would still be territorial governments using force to impose order on territory delimited by fences. But individual human beings would be so empowered through online communities, sovereign States on the Internet, that humanity will be able to reduce the role of the territorial governments to a role comparable to large property management firms.
IOW, the solution that I envision does not involve the destruction of property rights, including the right of a culture to seize territory for itself. My vision would accomplish the same goal (justice) by empowering every human being on the planet so that the territorial nations would have to compete with each other to attract residents.
It's ovious that if, so to speak, the switch will be turned off right here right now, there will be chaos and mayhem and all these things, but it's easy to say that's "humanity's" fault, without considering the deep programming we have been subjected to. That said, most of the people who are forced to migrate don't do that because they fancy it...they'd stay the heck in their own land if they were left in peace, while instead our controllers are causing all these wars and plundering to cause social and racial tensions in the west for their own agenda...never forget that.
Your remarks align well with my own thinking. But however you understand the evil in human society to operate, the important question is, "What are you personally willing to do about it?"
I have a plan that fully respects everyone's rights, including civil and property rights. My plan is lawful, simple, effective, and fun. When will people say, "Show me." and then, after being shown, say, "Count me in!"?
