Starting a space company to enrich yourself sounds like a very weird thing to do if you only care about money.
Also Elon lies all the time. He's even lying about playing games.
He's just trying to get money and power. Maybe he's doing some stuff that interests him on the side but he really doesn't care about you specifically.

I believe his motivations are beyond getting rich. At some point in life money become means to goals, and goals are driven by real motivation.
They are now about acquiring power and respect from other people, after he became rich and everyone started making fun of him.
It's a PR stunt. He pays someone to play for him and level up his account. Then, he plays for a bit and it's painfully obvious that he's inexperienced.
He doesn't take criticism very well either. He recently removed a live streamers Twitter verification for pointing out his lack of skill. How's that for a "free speech" platform?
Elon is extremely partisan, insecure, and rich. That's it.
