This is a well known fact in secure system design. Most people just click through dialogs. If you must get their attention you have to make the dialog huge and scary but then people will usually just turn back instead of reading. Scary dialogs make it seem like you should never say OK.

And not just secure system design.

“Undo” is powerful in any app, not just because it can roll a change back with a single click, but because scary dialog boxes (“Really, really REALLY delete this file? It can not be recovered once deleted, so check this box saying you know what you’re doing before clicking OK”) don’t work for regular apps, either.

How would you undo a crypto transfer, and is that a feature that fits in that system?

There are ways it could be built into the contract. But most don't support that operation today.

On whose authority and why? In this case the customer was promised a product they didn't get. And with traditional banking usually it's the other way around, businesses have to live with chargebacks for products they sell to people with stolen card info.

Always someone getting burned, but in this case it's the "idiots" for lack of better word. Don't try to make cryptocurrencies work like fiat, that's exactly the kind of problems they're trying to solve.

And let's say someone implements your solution, years later you will read how a bad actor did a chargeback for all the coins in those contracts and you will claim it was a retarded feature from the start.

> There are ways

You didn't even explore any of the options for different types of "undo" operations that could be possible in contracts. You seemed to simply assume recreating the exact same situation that exists in traditional finance and responded based on that.

There are several other ways of doing it that I can think of, all with their own pros and cons. There are even a couple that have already been applied in crypto that I can think of and I'm sure many that I'm not aware of.

And why would you assume I even meant "reimplement traditional chargebacks as they are today"? My recommendation: Hold off on forming strong opinions too early in the process of learning about something.

How about an example? I still don't see how it's possible in a decentralized system but go ahead prove me wrong. I'm not trying to be offensive I'm genuinely curious.
