Except it's hard to argue that Elon Musk does anything for profit. Both Tesla and SpaceX are examples of businesses set up to disrupt an industry and worry about money later.
I agree that he does not see the value of using money as a scoring system for his success, but making a profit, I am sure he is very interested in that. Profitable ventures are how he had the $100 million to create SpaceX. Profits of venture after venture until he acquired enough capital to actually start and fund a new aerospace company and be the largest investor in Tesla.
