That's why I see crypto tokenization as an important step towards having another "financial material" to work with. It doesn't commandeer enforcement at a global level, so it doesn't compete with governments on their own terms, but it can help build trust at scale by being designed around the trustless scenario, which reduces reliance on enforcement and bureaucratic methodology in many applications. Crypto projects with a focus on achieving good governance are some of the most promising out there, even as they are hidden in the endless waves of scams.
