You're definitely right, but I think Bezos is thinking long term. In 100 years smelting of metals mined on the moon might take place in space. Heavy industry growth might be limited to space another 100 years after that. He's glossing over the short term, but I'm all for having diversity amongst billionaires. If two of them are obsessed with space, but more have philanthropic aims, them so be it. I love the way Musk is planning a multi use rocket in the BFR, and the space colonies Bezos has envisaged, but I also hope that coal and natural gas use (and meat eating) can be reduced as soon as possible.
