It is only you that think the CSA is going to have no money and you have never made anything like a convincing case to me. In every post I have read on the matter CSA debt is vastly inflated by including both junk bonds and currency in circulationin the debt which is completely unjustified.{/quote]
Read Look Away by William C Davis. In actual history, the Confederate government accumulated $2.7 billion in public debt. (This number does not include the public debt of individual Confederate states.) Confederate graybacks were not like modern currency, they were Treasury Notes, redeemable at interest within 6 months of the end of the war. Just that interest would have been $120 million. (For contrast, government revenue for the entire US in 1860 was $52 million.)
Neither have I seen anything to suggest that the CSA's credit would be bad. It has export goods. It is an excellent prospect for investment and it has several agricultural and primary products booms comming over the fifteen years after independence. It is going to be a wealthy country.
In actual history the American South had all of that going for it, yet it was significantly poorer than the rest of the United States. An independent Confederacy will have the added burdens of $2.7 billion in public debt, a weaker currency, and 10% of their manpower having left the country.
Yes on the right terms it can buy all of the larger elements of a navy from the British and French and build smaller ones for itself.
The Union had a larger population, a smaller federal government, about 40% of the per capita public debt, greater population growth, better infrastructure, an established navy, an established shipbuilding industry, naval shipyards, and the majority of the former US coal.
If the Confederacy starts a naval arms race, the Union will win. European powers with colonies in the area (Britain, France, Spain) would probably be wary of Confederate naval expansion as well.
Again I question your assumption that the Union would be particularly wealthy after CSA independence. I think it is going to be pretty poor for a couple of decades in many scenarios.
How wealthy the Union is after the Civil War is a matter of debate. The Confederacy ending up better off than the Union will require the Confederacy exceed the Meiji Restoration in political and economic advancement while the Union simultaneously makes a series of blunders that makes modern Greece look like financial wizards.
