But as soon as there's a conversion to/from fiat or anything else in the real world, you have to trust whatever exchange or vendor you're dealing with. That means it's still a system that requires trust. With cash and banks I can go to the legal system to get issues with trust violation addressed. With crypto, I'm up shit's creek with no recourse when the exchange I used gave my tokens away or my computer was hacked with malware. This is not exactly "better" by any stretch of things. For many people it is turning out to be immensely worse.
