Frankly, his proposal sounds tempting to me. I especially like the part about my hometown:
New Orleans might have to be made a “free city,” like Danzig (now Gdańsk) between the world wars.
I'm not sure how NOLA would fare after independence (Gdansk did not fare well), but at least we would not have the US government to blame anymore. Having said that, some New Orleanians might prefer the status of a French colony to independence.
