I listed off a bunch of examples where banks literally took poeples money or prevented them from having it. If you are unaware of the multitude of times where the government takes peoples assets via immenent domain, or freezing funds when they exercise their rights, or literally attack their peaceful groups, I guess I can't help you, you don't need an economic lesson, you just need lessons in history and current events.

Rug pulls, ponzi schemes, hacks and so forth have nothing to do with blockchain and ALL of those things happen with banking systems and fiat money. In fact they happen more often and until VERY recently to far greater amounts. Heck north Korea almost stole a billion freaking dollars form bangladesh, but the 100 million they got away with isn't too shabby.

You have seriously confused the trustless natures of transaction verification in blockchain, with blockchain based projects that tend to be trusted and centralized (celsuis, terra, etc etc.... those failures are examples of the OLD trusted systems failing)
