Well, I mean that's a lie. "Good intentions don't make rocket fuel." The first rocket that was ever designed was designed specifically to go to space. It was used in WW2 by the Nazis but its creator said "The rocket worked perfectly, but it fell on the wrong planet." Those good intentions are needed for every step of space exploration. You don't get to suddenly become a rampant narcissistic, misogynistic, arrogant piece of human garbage the second that you clear the gravity well of your home planet. You hold true to those purposes because they will inform your every decision. If you start doing horrible things in the pursuit of a lofty goal, you corrupt that goal and all actions you take in the future. You will be looking through things in a dirtied, bloodied lens. Or, as someone once put it far better...

“You cannot explain away a wantonly immoral act because you think that it is connected to some higher purpose.” - Captain Jean-Luc Picard

Whether you do good things or bad things is who you are. If you start taking terrible actions then you become a terrible person. Or, as the man again once said...

"It's our morality that defines us. It's part of the truth of our existence."

Then there's the fact that Elon constantly shits on everyone below him. Guess what? There's a few quotes for that too. Here are my favorites.

"No being is so important that he can usurp the rights of another."

"You know, there are some words I've known since I was a schoolboy. "With the first link, the chain is forged. The first speech censured, the first thought forbidden, the first freedom denied, chains us all irrevocably." Those words were uttered by Judge Aaron Satie as wisdom and warning. The first time any man's freedom is trodden on, we're all damaged."

Or what about this interaction between Worf and Picard?

Picard: We think we've come so far. Torture of heretics, burning of witches, is all ancient history. Then, before you can blink an eye, suddenly, it threatens to start all over again.

Worf: I believed her. I... helped her. I did not see her for what she was.

Picard: Mr. Worf, villains who twirl their moustache are easy to spot. Those who clothe themselves in good deeds are well-camouflaged.

Worf: I think... after yesterday people will not be so ready to trust her.

Picard: Maybe. But she, or someone like her, will always be with us. Waiting for the right climate in which to flourish, spreading fear in the name of righteousness. [...] Vigilance, Mr. Worf. That is the price we must continually pay.

Now lemme top all this ramble off with one final slightly edited quote to cement my point.

The first duty of every Star Trek fan is to the truth, whether it's scientific truth or historical truth or personal truth! It is the guiding principle on which Starfleet is based! If you can't find it within yourself to stand up and tell the truth about what happened, you don't deserve to wear that cosplay.

I always love that logic ... our planet is too dangerous and dying, so we have to leave to make sure we survive

At this point in our evolution ... we would ensure our long term survival in our galaxy if we stayed put and maintained our current environment. It's the only liveable atmosphere, environment and planet that we know of that we can live on and have access to.

How are we going to restart life on Mars where there is no atmosphere or resources when we're doing such a terrible job maintaining the existing atmosphere and environment we were born into?

I always like burning house metaphors .... space exploration to save our species at this point in time is like burning your house down, telling everyone you can't live there any more and saying that you're leaving to go live somewhere else where you can decorate a better bedroom. Except your burning house is located in an isolated desert with no shelter for hundreds of miles around.
