And if his 100M$ loan and the fact that he dumped all of his wealth and then some into both companies, Elon making money should translate into the companies making money as he is sure to quickly turn around and reinvest his wealth back into his passion.
This was one of my biggest appeals about Elon Musk in general when I first started looking into the guy back in the day. He isn't like most Million/Billionaires who were happy to make their money and then call it quits. He had on more than one occasion an out that he could have taken and retired to his own private Island, but instead he keeps rolling the dice and going all-in, which is why I admire him so much. His current "wealth" is all on paper, and should he be able to access any of that money (for one reason or another) you can bet that he would throw it back into either a current or future venture.
He talked in one interview about how he figured out how to live on like 1$ a day (way back when), so he was like, yeah, OK, If everything goes belly up I can still eat, so let's do this! If only more billionaires had his risk appetite the world would be a very different place.
I said all that to say, I agree with the assessment that the general success of Elon should translate into success specifically for Tesla, even if it is through shear brute-force of him dumping extra money to keep things going until the problems find solutions.
This. Plus the fact it just adds another notch to his silicon valley street cred - if a battlecry goes out how many leaders in tech, like Larry Page, would be willing to put their fortunes towards Musk's visions?
Also, I expect as SpaceX accomplishes really cool things the aura extends to Tesla. "We landed astronauts in a Dragon V2 on the moon wow! What, they use the same touchscreen as a Model S? Gotta check out their store!"
