This also depends on your definition of value. Sure Elon is good for promotion and endlessly raising funds, but how do you compare that to actually engineering the product, producing it etc.
If Tesla (or any other company) doesn't keep producing products, there is no more company? I realise that raising capital is necessary but my point was that both aspects of the company are "valuable" and that it is hard to say yes person X is definitely 1000x more valuable although they are working in different departments.
