Are you sure? I like Elon Musk quite a bit, and even I don't think he should go around telling politicians what to do. That's not what we as a society have businesspeople for.
I agree with you. However, there is the world we want and the world we live in. Until we have an actual democracy (which likely won't have billionaires, look into what happens in popular movements in the past) then Musk has an outside responsibility to society because he has outsized power.
