The problems that libertarians are worried about are explored to their ultimate dystopian consequences by non libertarian, Soviet-born Dmitry Orlov. He analyses the possibility of total societal collapse (a scenario where personal freedom would be threatened as much as with the superficially apparent opposite of totalitarian state) and comes very logically to the conclusion that a seaworthy solar propelled vessel (a sailboat) would be the best chance of survival.
The New Age of Sail by Dmitry Orlov
Why a sail boat and not other boat?
In addition to the more obvious aspect of being powered by the wind, a sailboat is also
an enclosed bubble/capsule living space able to withstand rollover in the worst circumstances (with mast loss) and otherwise able to traverse the open ocean and engage in economic activity as it has a wave piercing bow, and a docking platform in the protected aft.
Faced with the alternative of total collapse it makes sense as emergency measure to equip oneself with a sailboat, but it’s not a total or viable solution.
Sailboats require serious maintenance and their storage space is very limited.
If our common goal is to engineer an “opt out” from the existing states which have encroached all dry land and all protected bays, we need a further solution:
A floating place to dock sailboats, maintain them, store and trade supplies and even house people who would not be safe in a sailboat.
The smallest, easiest, conceivable version of this would be a small underwater sphere with a pier. like this:
Another option would be an atoll shaped floating platform, like a “Ramform Island”:
What would be your option?
