Marshall, back to what you were saying about self-sufficiency. Your idea can and will work, however like others have mentioned, you need a lot of people. The countries I have seen that have had success with what you are saying generally have 45-50 million people. I, personally, have done this before, If I remember correctly, I had roughly 45 million people with about 60 corps providing my country with what it needed. However, once you setup your country, for example one of my previous countries that I mentioned above, you don't usually make above 10B in profit each month leaving you with little room for expansion of infrastructure or funding for a war.
