I am not talking about cost at all. More about commercial interests vs public interests.

Elon Musks stance on fighting climate change seems to be that we can just solve the problem with technology without doing much about endless consumption and waste, failing that mitigating the issues for whoever can afford to, starting with biohazard mode on your Tesla and ending with escaping to Mars. I don't want all our space tech in the hands of such a person. Happy to see China is still investing more heavily.
