You are missing the point. People that choose Python do just that, they choose Python. The use of JS is very often not a matter of choice, because it's the only language supported in browsers.

People that choose Python _chose_ a language that doesn't have static typing.

People that want to write code that runs in a Web browser are locked in to Javascript, so they're "locked in" to JS; I can't think of a platform where the only option is to use Python.
