In their model the only benefit of talent is it makes you more likely to double your wealth given luck. This means that they assume luck is needed for advancement while talent is not. Hence they assume that luck is more important than talent, and it's unsurprising that they see the result. Likewise the power distribution is built in. Power distributions are created by multiplicative laws and the only ways wealth changes in this model are multiplication and division. This means they also assume the power distribution they claim to discover. It's definitely very hard to build models that match reality, but this one doesn't really seem to try and it's outcomes are so predictable they don't offer meaningful insight. Luck surely plays a huge role in success, but something like longitudinal studies where we measure the abilities of children and then follow their outcomes are likely far more insightful. |

Which is clearly true. You can be as talented as you like, but talent without a corresponding opportunity to use that talent for monetary gain obviously yields no wealth. There's nothing objectionable here.
It's also widely believed that greater talent makes one more successful at exploiting opportunities, and the paper accepts this premise in order to test it.
Now you can quibble that perhaps the random variable governing opportunities is not independent of talent, in that, those with more talent are simply presented with more opportunities. Perhaps that's true.
But the paper actually shows that our world is also consistent with the hypothesis that opportunities are completely random.

I think you're looking at this wrong. The power distribution is not the discovery, the discovery is that what we see in real life is consistent with such a simple formulation based on a small number of factors where wealth disparity is largely dominated by luck.
Perhaps that's not actually the case in reality, but we now know that it's absolutely not impossible, which some previously believed.

These aren't mutually exclusive. Modelling and empirical studies both yield insights.
