When UUs die their souls come to a fork in the road, where they see a sign. UUs all go to the discussion group. Now, among libertarians, I often meet one who stubbornly debates some point of purity. It seems to me that these libertarians would want nothing to do with a new free nation unless their condition X were met. But I think liberty is a relative thing.
Some countries are more free than others.
More free countries are better places to live than less free countries. And I would choose to go to that country if it became an option while there appeared to be no immediate promise of getting an even greater reduction in government. I think that we, who study the history of constitutions from a libertarian viewpoint, have learned enough that we can constitute a new nation with greater liberty, and with more protections for liberty, than ever before in history. But I do not expect that we are perfect, just yet.
