Why there's no libertarian nation on Earth yet

A nation is a group of people. A nation state is what the world is mostly made up of now. For example, you can have the German nation without having a unified nation state (west vs east). Also, ancient Greece was filled with city states but it was a Greek nation.

Depends on how you use the word.

Depends.

If you consider Minarchists as “true libertarians,” then they would most likely be in favor of nations.

If you consider anarchist as “true libertarians,” then they would most likely see a nation as arbitrary and antithetical to their beliefs.

From wiktionary:

It just depends how you are using the term. If you are using it as a synonym for nation state, or just state, then obviously no anarchist can support the idea of a nation. But the idea of a people unified by culture and language, among other things, that idea is compatible with anarchism.

If a nation is just a group of people unified by culture and language (philosophy?) then a libertarian nation already exists although in a disconnected, disparate form geographically speaking.

Meh, I thought that was implied : /

I didn’t read the OP, but I’m sure that nation = state was what the definition that people were using, but I was just throwing it out there that the idea of a nation =/= state is in fact valid. In theory, America (or any country) could become a libertarian nation without having some kind of statist system.

We can hope.
