Twirlcan:But states are not all powerful.
I guess I am just more of a pessimist. I don't believe that any free society will ever come from the ashes of an old one. Time and time again through history we see powerful governments collapse...only to be replaced by another powerful government.
There are two reasons for this. One, people are cowards. They fear change, and when a corrupt leader or ruling junta collapses all they want is for things to go back "the way they were". They are not thinking "oh, here is my chance to implement a new type of free society". They are thinking "I don't care who is in charge, as long as I can feed my family". The likelihood of any libertarian finding an existing country, causing it's collapse, and then forging a new society based on libertarian principles in its wake is nil. You might as well hope for a libertarian to be elected president of the US in November by a surprise write-in third-party vote.
Second, land is rare. There is a reason why they call the term a "vaccuum"...there are not many forces stronger than it. As soon as any existing state falls apart, other states swarm all over it. Even if some libertarian somewhere found a country in the process of collapse and tried to take it over they would have plenty of competition...from well-armed, powerful, and rich neighbors who would much rather take over that country's assets then let them be part of a grand social experiment in libertarian principles.
No, the only chance there is of any libertarian...or libertarian-like...society being formed is for something to start fresh...free of all the baggage that comes with any existing state. Since all the land is taken, you have no choice but to start in the only unclaimed area of the planet...the oceans.
The other great thing about starting a floating colony is that everyone who is part of your new society is there by intent. There is no need to convert the cowardly masses. You start a new society, and you invite anyone who shares your principles to come along. You start off with a strong population base that already agrees on a basic set of rules and principles.
