I don't see the problem in guessing what approaches would have been possible in which situation and wondering about it. Learning something new about a topic you wouldn't encounter elsewhere in discussion. Because after all, isn't that why we are here in the first place? That aside, the idea of raising the water was valid and was ( luckily) available though nature. It wasn't mentioned before it appeared here. See: High tides. And cofferdams could have been used when the situation was much worse. But the logistics of organizing it would have been painful ( https://news.ycombinator.com/item?id=26587692 https://news.ycombinator.com/item?id=26587692 ) Which is what followed when bringing up: "temporal dams" surrounding the ship. Which is obviously very different than "building giant elaborate dams". But ofc, not everyone actually reads the things that are said and some just interpret their own prejudice. Degrading the whole discussion.
