Tough to really throw even partial blame for global warming on chemical propulsion launches. Funny thought, though. :)

Go fast and break stuff is a viable way to rapidly iterate inside a known box, which is really what spaceX did with dragon and falcon. NASA gave them a big head start - they more or less had an engine design, more or less knew how to build a gn&c (even for propulsive return), more or less knew how to build the sticks… just wasn’t efficient or cost-effective. Cutting bits off to see if the overall system still operates is kinda how the relationship between govt and industry is supposed to work.

Starship isn’t iterating inside a known box. It’s not a smarter cheaper version of existing tech, it’s a whole new thing that Elon just kinda spoke into existence. It must be fun to have that kind of money and power, but it doesn’t mean the idea will ever actually work - and this is where the deliberate, methodical process that NASA uses becomes more valuable.

What’ll be interesting is when SpaceX starts missing payment milestones. I think they’ve gotten some grace in the past. Not sure the current environment is as permissive. Wouldn’t be surprised if that’s part of why Elon wants to shift the goalposts to Mars - it’d give him more time to sort out some of the fundamental challenges with his concept.
