The issue is that your example fails to be analogous in that no one has ever had a winning strategy to becoming a billionaire. If there was an implementable strategy that anyone could do if they were unethical enough, there would be a hell of a lot more than 3000 of them in the world.
The only way to become a big-apple-person in your example is to find the treasure trove. You aren’t physically capable of beating people up quick enough to steal all their apples. No current billionaire strategized their way into that position. They all found the apple lotto pile. Sometimes that pile is called Minecraft, and sometimes it’s called Amazon, but they all became billionaires by finding a giant pile of apples.
And absolutely not on any strategy that makes more than 2% overtaking you. If I have 200billion dollars, at 2%, and you have 1billion at 10%, it’s gonna take you nearly half a century to even reach my starting balance. Yeah, sure, you’ll overtake me eventually, but that’s more likely to happen because I died than because you ended up making more money than me.
And this is once again you moving the goalposts. What does it mean to “maintain that level of wealth”? Stay the richest for 5 years? 10? 20? 100? Your whole life? What if I die the day after I got the money? Do I have to invent an immortality potion to ever be able to claim to have “maintained” it? If you are unwilling to define what you mean by that, I’ll just be aiming for an ever expanding, nebulous, “that’s not quite enough.”
