I will agree with you that Elon Musk shouldn’t be praised to the height that he is. That is the obvious point of this subreddit.

Your second point holds a lack of understanding to the current issues of the economics of climate change. Money will not solve everything. I leave you to discover that with your own initiative.

Finally, Your third argument follows the point I mentioned above. Become educated on the issue before arguing your point. Net worth is not equivalent to political/environmental impact in the way you describe, no matter how much you want to believe such an argument. Your worldview is clearly heavily influenced by the capitalism you grew up observing.
