Pretty low quality article that doesn't consider such things, or the concept of fungibility and private protocols compared to mixing, or the history of how money was always expected to be fungible so this modern culture is unusual, etc... so many things to say, and so few people that are aware
Seems like a propaganda piece since it speaks entirely as mixing=bad. Would ask the author how he would feel about publishing all his bank statements publicly online, and if he would feel safe having address leaked and large crypto holdings that were public
