In the early 1970s, there was an attempt to create a sovereign micro-nation in the South Pacific, on the Minerva Reefs. You can read more detailed accounts of the Republic of Minerva at the articles linked from this post, if you are interested. The Republic had its own flag, its own currency, and it issued the very interesting coins illustrated at the top of this post to help raise money for the project. I bought some of these coins in 1973, and still have them hidden away today.
The Republic of Minerva was going to be a Libertarian nation with as little government and taxation as possible. Before the tiny, artificial land mass was invaded by neighbouring Tonga, I actually contemplated getting involved in the project and moving there someday. The idea of minimal government, minimal taxation, and living among like-minded people intrigued me. Sadly, the dream was not to be. I still take out my Minervan coins on occasion and wonder what might exist in that location today, had things progressed as planned.
Realistically, of course, I know that any nation along these libertarian lines could never last for long. Someone, somewhere, would take offense at the idea that people could live together in harmony without the guidance of a Ministry of Meddling and a Ministry of Income Redistribution, and would make it their life's work to 'improve' the fledgling nation. Soon, other malcontents and freeloaders would pile on and complain that who-knows-what was or wasn't taking place. Eventually enough people with the notion that 'something-should-be-done-about-that' would prevail on a nearby government with enough guns and manpower, and they would bring the enterprise to an end.
So, why bother even trying something like this?
Libertarians like to be free. It is not natural to have others pull our strings, to make us dance according to their whims. It is not natural to be forced to pay for things of which we don't approve and to support those too lazy to take care of themselves. And some of us have a little bit of Don Quixote in us. We have a soft spot for lost causes. We dream and hope that someday, under just the right circumstances, something that we envision could actually exist somewhere in the world. Or maybe on the moon, or on another planet. Someday, somewhere, there will be a society of free people.
