I genuinely do not understand this example. What is spacex actually doing? And why do they even have money in “long tail markets” at all?

I don’t know anything about this specific case but it is common for manufacturers to have currency needs in long tail markets to facilitate payments to subsidiaries, vendors and employees in all the places they do business.
