At the end of the day, it is a video which serves to further actual discussion. There are going to be points where he gets "carried away" because that's the entire point - simply listing the facts doesn't really contribute much, the video uses the facts that we have and extrapolates a conclusion. Crypto currencies, in their current state, are just learning WHY centralized systems exist. While we all would love to be decentralized all the time (and some decentralization is a good idea!), these people end up just using centralized systems to more easily manage their "decentralized" systems.

And really, I don't think this should be surprising for most people. This is exactly what happened to Email - a decentralized system that also just happens to be 90% controlled by 1 company because people much prefer the benefits of centralization to the "freedoms" of decentralization.
