I mean, I certainly think it’s possible to become the richest man on earth through purely ethical means. It’s wildly, incredibly unlikely, but strictly possible.
You could become a recording artist that self publishes your own music, only distribute online, and become unprecedented levels of popular. Sell each mp3 for $5 and sell a few trillion of them.
Is that likely? Absolutely not. Exceedingly unlikely. But becoming a muliti-billionaire in general is exceedingly unlikely. This is one of the lesser likely ways for sure, but it’s fathomable, at least in the sense that it’s a coherent narrative that strictly could occur.
What about that scenario is strictly impossible? Not vanishingly unlikely, but literally could not happen?
