If the corporation goes bankrupt, does that make the contract invalid/dissolved/Insolvent? How far back can a country's bankruptcy court claw back? Centuries? Does it take a war to cancel the contract? What if we dissolve the currency instead? If there is no Rothschild currency, how can a debt be repaid? Assets? OK, we give you that hell hole DC back. In return, pay us for WW1 and WW2 that we fought on your behalf. Back to reality, If the congress didn't have the authority to enter that contract, how could that contract be valid? They would have entered the contract fraudulently, and fraud vitiates everything.
This is fun!
