So what's the alternative? I can not trust global institutions all I want and rely on alternatives for everything, but would I be able to trust the alternatives, and what would stop powerful institutions from butting in all the same? Wouldn't it be just easier to fix our institutions so that we can trust and rely on them? The crypto economy for example is full of sharks. It's a bigger, insider, scammer dog eats smaller, outsider, bagholder dog world and there is no fixing it. It's a zero sum game. It's unsustainable. It's inhumane. It's too simple to hold up any practical economy at scale.
