I'm familiar with many supporting arguments for the Free State Project. One is that some of us would like freedom sooner rather than later, and the FSP is the best effort so far to accomplish that. Another is that we're spread too thin, a distinct minority, and that maybe aggregating a bit might help reach critical mass. Yet a third (which I don't think is crazy) is that we want a stronghold that will be safe from the NWO if the shit hits the fan.
I agree with all of these, but my favorite of all seems to never come up. The most important reason to support (and participate in) the FSP is to show the world what freedom is, because no one currently alive has ever seen it.
Think about it. When in recorded human history has there been freedom on a large and visible scale (I'm discounting small or remote populations that were left undisturbed)? In Greece, thousands of years ago, and in America, briefly, for less than a century after the War of Independence. That's... pretty much it.
We talk about liberty, and we mean it more than the empty rhetoric taught in school and spewed forth by politicians, but even to us, it is still an idea, an intangible. We know we're right, but we can't prove it. We know where we want to go, but we can point to it and say "behold, this is what freedom is". No one alive, not even us, has ever really tasted or even witnessed freedom. By that standard, landing on the moon was an easier task than bringing freedom to the world - even a small part of it.
I've instinctively been libertarian minded all my life, but I only started taking politics seriously about four years ago, and only dedicated myself fully to the pursuit of liberty one year ago. I've read history and philosophy, studied economics, undertook to understand human nature and organizational behavior, and after much consideration, comfortably arrived at my current understanding of liberty and dedication to achieving it. But I, and others like me, are like the Wright Brothers in 1899 - we've never actually flown.
When we finally take flight, we will have vindicated both our efforts and our values, but just as importantly, we will have shown the world that freedom can be real. In the words of Adelai Niska, "now my reputation with you is fact, is solid".
There is no substitute for that. No book, no documentary, no campaign, no campfire chat will compare to the undisputable, unignorable, it-tastes-so-good tangible proof of the practicality and achievability of freedom. Then we take the Pepsi challenge, and watch the people wake up to the contrast.
Nothing else will work. You'll have an easier time selling shares in a startup with no working products than trying to persuade people to your viewpoints on government on reason alone.
To sum up - "show me the money".
PS-And because I'm such a Joss Whedon junky, I'll throw in one more quote, this one by Angel: "We live as though the world is as it should be, to show the world what it can be."
