I'm not following.
You will not find trust _in people_ anywhere in modern society.
Banks certify transactions, governments certify identity. We can go on and on here. Whole swathes of law around this topic too lol (see: fraud).
Crypto isn't about not trusting people, it's about not needing to trust strangers.
Some of them are scams, ironically, but when there's money involved... well it's pretty stupid to _just_ trust people.
Unless I've missed something?
