Your argument was that some IDE features are really really needed. > There are good reasons industry best practices include things like code reviews, testing, and staging environments. But I suppose, if you are going to ignore all of these, then the lack of type safety is the least of your concerns. You are doing a strawman fallacy. I never ever spoke about having or not having code reviews, and separate testing and staging environments. All of these are also necessary, and what in the world does this has to do with static typing? Testing and staging environments are required and doable using any programming language.
