I get your point, but it's more complex than that. If the investors get fed up with the volatility (read: unwarranted SP drops) of the company, they start selling, dropping the price lower. Workers compensation is partly in stock equity, and for them seeing the stock price drop when they're busting their asses is demoralising, and that's again bad for the company. Severe SP drops can ultimately lead to the company becoming insolvent, artificially so but still. And so the way operations are run is just as important as the cutting-edge technology employed by the company, the level of talent and the drive of the man in charge. It's a package deal, and all parts are important.
It’s not more complex. If investors don’t want to invest, Tesla goes back to being a private company. Employees will continue to have stock options. Elon be happy camper. Onward and upward.
