As far as the 10 billion "freedomship"? Whats the point? Why not use that money to hire some mercenaries and go take over some 3rd world country that actually has natural resources you can exploit?
Or better yet buy an election. Lets say it costs you 10 million in funding to win a senate seat. And 2 million to win a seat in the house of representatives. Thats 2 billion for the congress. Which leaves you 8 billion to win the presidency. Even Obama spent less than a billion and his ads were everywhere, surely you could win with 8.
Then for 4-8 years you'll have a carte blanche to change policy to whatever it is you wish.
The problem is that all these "freedom" type ventures, are usually a hobby of the fringe, and they don't have the money to actually do anything they dream about. If the Liberterian party had a 10 billion dollar pocket book, we'd have more than the handful of Liberterians in congress. And these fringers wouldn't have to go looking offshore to try their pipe dreams.
And thats coming from someone who donated money to Ron Paul. Sure I knew he couldn't win...but it doesn't hurt to have an extra point of view in the limelight
