I think his biggest obstacle is himself. He can recover from this, but it would require for him to stop being so aggressive and even hostile towards anyone who offers advice or criticism, as well as learning to cope with people who oppose him. He would also need to be more cooperative with others and even be willing to help others without any direct or immediate gain to himself.
I don't think he can do that. His original approach, which involved using and abusing others and always looking to come out with a net gain, worked for so long that he would have to deal with an overwhelming cognitive dissonance if he took a long-term approach that required him to make short-term sacrifices and to elevate others instead of pushing them down. He may never reach a point where he realizes that his need to be important and recognized is hurting his efforts (and ironically, is working against his desire).
But, sure. Add a higher tier to your Patreon, that should fix things.
