I've mostly addressed this in the siblings comments. Mars has all the same resources and more. The way humans went from the moon's orbit to surface is so far off from how it would be done today I would hardly call it and MVP. Both are too far for any meaningful emergency response. I believe the ongoing work with starship debunks your claim of an "un-funded wank-fantasy". The moon also has a disturbingly high failure rate for the unmanned attempts.
