If you stick to just a few units throughout the system (ideally, use a consistent base unit everywhere and convert any external measurements to it), you can avoid the rest of the problems.

Static typing is great, of course, I just don't agree that this can't be solved to almost the same level with languages with dynamic typing.

The keyword is “almost”, and whether you need stricter typing depends how much you care about software correctness (or to be pedantic, the class of problems that the typing system can fix for you in the language in question).
