I hope there is some plan to thwart this, as New Orleans is my favorite city on Earth. Truly unique culture and history against the homogenization and suburbanization of America. If you’ve never visited, please go.
The tourist portions of the city are created and supported by the surrounding population; they generate the parade, music, and celebratory culture year round. We can't just abandon or move the residential areas and keep the rest intact without it becoming a Disney main street facsimile version mocking what it once was, which would destroy the tourist appeal outright.
I agree with you except for the last part, NOLA is gonna get frog boiled into exactly that Disney facsimile, people have shown they aren't discriminating about authenticity to the degree that you are.
I was thinking the same thing. It truly is a magical place and unlike any other city in America I've been to. I think relocation is best for the safety of the residents (obviously), but I can't help but think "New Orleans 2.0" would end up being just another city. Unless someone comes up with a way to pick the whole thing up and move it, I strongly recommended visiting before it's gone.
