What most people will offer as the result: Some economic results, a stagnant economy where no borrowing is possible. Loss of all ratings from the world bank. Debt repayment systems that cripple economic growth.

What actually tends to happen historically: Massive inflation and money loss due to it exiting the system. Fascism, mass killing, militarization of Government, invasions of smaller countries. Being a pariah state. Ultimately a world war against you.
