Environmental regulations in the US are such that scrapping the ship would turn out to be unbelievably expensive.
Only place left in the world where a ship can be scrapped and make money off it is India (you may have seen the documentaries on it, they drag the ships up on the beach); however, it would be extremely easy for, say, Chicom agents to crawl all over the ship and examine it if that were done.
Those documentaries were incredible.
Every man for himself. Cutting torches and hand labor - amazing how it's done there.
