I guess this is my disconnect or naïveté, but I thought the whole point of crypto is that it’s fairly traceable - obviously, there’s no decentralized way to address fraud, but couldn’t we have a decentralized report system that can warn people before sending tokens to known malicious actors?
"Often" word is used because it also covers the case of small transactions. As transactions get bigger, systems get slower. I have had personal phone calls from bank to ensure I wanted to send big sum of money.
