I like being thin and healthy and I also like Pizza and Beer. If would be great if I could have both things, but in the real world actions have consequences and eating pizza and beer all day will make me fat and unhealthy.
I'm not saying Elon is a perfect CEO and that is impossible for someone to do a better job at Tesla. But in the real world actions have consequences and the current state of Tesla is due to the previous actions of Elon.
For example, he fired a long time assistant after she demanded 4 million dollars in compensation. You can feel sorry for the assistant, for getting fired after doing a great job, but that is 4 million dollars that was then able to be invested into the rest of the business. You can't have it both ways. You can't fire Elon and expect that magically another CEO that you like much better as a person will also produce the same results.
