If his portfolio earns more than the car loan interest on average, then it's a good idea to keep holding and not pay off the loan. This is because he is statistically likely to keep making money. Asking "what if there is a downturn" is nonsensical because the negative situation is less likely than the positive situation. It's like if I offered you an asset that has 80% chance to double in value and 20% chance to halve in value and you turned it down because "what if it goes down in value." It isn't rational thinking.
That level of risk avoidance might make sense if you have literally no other money and you need that cash to buy food, but the guy you replied to obviously has a secure enough situation that taking gambles with positive expected value is smart behavior.
Plus, having an emergency need for money like a medical issue or a storm damaging your house is both more likely and more catastrophic than a massive market failure. Having more liquidity makes a person better able to deal with these situations without incurring extra losses. So even if he's extremely risk avoidant his situation is still more secure and smarter than a man who has no assets or loans and just a car. That's why even corporations run by professionals to maximize profits and avoid risk will take out loans for their company cars rather than paying cash for them, despite also having cash on hand and a bunch of other assets including stock holdings that they could spend on the cars.
