I like the idea, but in a future with lots of blockchains this seems most valuable as a blueprint for building corporate governance structures using blockchain technology.
Not saying it's not gonna work, but the idea of a decentralized nation goes against the general understanding of what a "nation" is: an area of the earth in which a particular authority has used violence to ensure that the laws that they decide on are followed.
The example about liberland police near the end was illuminating in terms of the vision of what a decentralized state would look like. The idea of calling whichever police you see as most useful is cool, but when you take the concept of zero-barrier blockchain nation-states to its logical conclusion, what comes out is essentially a world full of non-localized, self-governing collections of people, each running on its own blockchain (or tangle?). I'll call them "block-nations". Because of competition, the "block-nations" will need to create some sort of value to offer to the rest of the world, in order to attract citizens. Assuming the evolution of this follows the evolution of other social systems, this will lead to particular block-nations being better at producing certain things than others, based on the skill-sets of their citizens.
But now we've gone past the block-nation, into what is effectively worker-owned and operated companies. Which is not a nation-state, as it operates through the forces of capitalism rather than the forces of violence.
Does this project have open source code, on a website or github? I'd love to see how they implement this.
