Satoshi left because he knew he was in danger if he was a public persona, he had nothing to gain. It would damage Bitcoin as a project with "a CEO".
Also, the point of Bitcoin is that we don't need "Wall Street CEO's" permission to grow. If they don't want to get involved, others will, and at some point they will be forced to join or sink.
If Wall Street doesn't make the most of this new opportunity, Silicon Valley will. As Jamie Dimon said about fintech "Silicon Valley is coming". At some point, they will see the lost revenue and get involved with crypto companies.
