Arnold Kling writes in TCS Daily:
The alternative ideology that I would propose might be called transnational libertarianism. The ideal libertarian world would have no economic borders. There would be no problem of illegal immigration, because all forms of immigration would be legal.
If transnational libertarianism were to become sufficiently popular to emerge as the ideology that determines the world’s institutions, then governments would be local rather than national. Their main role would be to prevent outbreaks of violence among individuals or groups. In the nightclub of life, government would be the bouncer, not the owner or the manager or the dance instructor or the disk jockey.
I don’t imagine it happening in my lifetime, but I can hope. Read the whole thing.
