Genuinely can't tell if you are trying to be sarcastic with the first sentence, but I'll just point out that Tesla can both have accomplished a lot as a company, been a net benefit for humanity, be wildly overvalued as a company, and have no real moat. They were the first automaker to put substantial money into selling EVs as a business and that gave them a first mover advantage that has now largely disappeared (but still exists in certain areas such as still having the best charging network).
