I still fail to understand, why, if they hate the current system so much, they simply don't take up a collection, pool their capital, buy an island somewhere, make treaties with the rest of the world to be left along for a century, and then they can reveal to the world the perfect Utopia.
Then they don't have to have corporations or cops and they can live the "From each according to their means, to each according to their needs" thing and show the rest of us how long we were.
But if they fail, that's it. They have to shut up about the Marxism and rebuild their lives.
