I didn't say "making mankind an interplanetary species" isn't his primary goal, I said that it's not the primary thing he wants to do. What he seems to want to do is be rich, father an absurd number of children with different women and be cheered on and celebrated by his fans and sycophants. He literally bought Twitter on a whim because he liked the attention he got there. He's obsessed with appearing "cool" ever since people called him "real life Tony Stark" and he let it get to his head even though his popularity massively took a nosedive shortly after.
