That's a great example! It illustrates the point in a better way than I tried to.
A necessary part of why types are so useful is that understanding the types is easier than understanding the code itself.
If the types become so complex that they start to get harder to understand than reading your code (e.g. C++ template errors can sometimes get this bad), then they are no longer helpful.
