I'll restate because both objections (which apparently skim instead of read) are missing the important point. Yes LLMs can run "what ifs" scenarios and build models.

However LLMs deal entirely in symbols. 100%. Humans can "world build" aside from this and in fact are often at their best doing so.

Did the first humans to use fire and some form of a wheel even have the capability to talk about it? Think about that.
