Blockchain is built from the ground up to prevent exactly one type of security vulnerability: man in the middle attacks. It is absolutely abysmal at protecting against any other form of attack. Anything that involves, say: social engineering, is fair game. After all it is YOUR fault if YOU leak personal information that can be used to destroy YOUR life. If that ends up in the blockchain its not MY fault, I cant do anything... what do you want me to do? change it? punish someone? oops sorry I cant!
Ultimately this form of thinking is the logical conclusion of "personal responsibility" arguments. Why criticize the system when you can instead pretend the problem is the individual? Crypto doesnt have philosophical issues, you are using the wrong wallet. It isnt MY fault that someone made an NFT containing your home address and bitcoin wallet ID, YOU trusted your information with the wrong service.
The ultimate scapegoat is blaming the end-user. At some point you need to take the L and at least admit these are oversights. Blockchain tech has been around for over a decade and it's had plenty of time to solve these problems but instead it has dug its heels in and said "no all of this is by design and good actually"
