I don't understand her arguments:
First, as a private company, Tesla will be unable to capitalize on its competitive advantages as rapidly and dramatically as it would as a public company, an important consideration given the network effects and natural geographic monopolies to which autonomous taxi and truck networks will submit.
Is she saying that Tesla won't be able to do equity financing? I think equity financing and leveraged debt got Tesla into trouble to begin with, it's what attracted the shorts who seem to have a ... willing ally at Moody's.
Second, in the private market, Tesla would lose the free publicity associated with your role as the CEO of the public company not only with the
bestselling mid-sized premium sedan in the US, but also arguably in the best position to launch a completely autonomous taxi network nationwide in the next few years.
Don't think this is true: Elon has no trouble getting publicity as the CEO of SpaceX.
What he wants to avoid is the volatility and short-termism of public markets, which is in large part enabled by being traded on an exchange where the rules are in favor of speculators and financial parasites.
For example why isn't it public information who the biggest Tesla shorts are? Is it UBS? If yes, shouldn't they be barred from attacking Tesla through covert means, due to the obvious conflict of interest? The identity of the largest investors is public - why not the identity of the largest anti-investors?
I think the final straw for Elon were the 9% layoffs in June. They were entirely unnecessary and were disruptive, the layoffs were only done to reach profitability faster.
