Thanks for sharing. I just binged the whole thing! Always a fan of Freakonomics. It did a pretty good job presenting both sides of the discussion.
I do have a bone to pick with any criticism of early adopters or the assertion of poor distribution. The podcast was misleading in this regard. Bitcoin launched with a price of ZERO. There was no pre mine, venture capital, or rich oligarchs backing the project. All coins initially mined were by people who believed in the project and wanted to participate with ZERO promise of financial gain. The bitcoins were worth almost nothing. There is a large chunk of whale holdings that are almost certainly lost coins which bears fail to acknowledge. Remember, these coins were worth nothing, so losing your keys to a fried hard drive or a lost piece of paper was extremely common. The podcast analysis also failed to discuss that large entities like exchanges or wrapped bitcoin, etc, and how they represent a portion of large holders. Depending on how you look at the data, you can easily come up with figures that show BTC to be better distributed then worldwide legacy system wealth.
Lastly, since BTC is a fixed monetary system, on chain data shows distribution continues to improve as the network grows. Conversely, the wealth inequality in our legacy system continues to favor the rich and feast on the poor.
