Immutability as a weakness


Debating with my brother tonight - he argues that immutability is a weakness in the real world because we don’t want mistakes or fraud to go unaddressed.

He’s saying that the risk of fraud through our regulated legacy trusted intermediaries (banks, visa, law firm trust accounts etc) is a lot lower than the risk of mistake or fraud for the average person transacting on an immutable blockchain.

What sayest thou?
