Exchanges actually useful to people in most countries kill accounts that they see depositing from coinjoins. Secondly, Coinjoins are also trivial to pierce. It does not provide serious privacy protections from a state adversary with resources and entire companies dedicated to analyzing coinjoins. Coinjoins are only useful if you want to pay for small things and never do something like “buy a house”, “pay rent” or “pay for your cancer treatment.”

Transparency is key, just like our ancestral diet, simple and unobstructed, no hidden additives.

It depends on what timescale you're looking at. I don't use KYC'd exchanges, nor would I, so has never been an issue for me. Coinjoins are as useful as the anonymity set. House/car sized payments are totally fine, war sized payments are not (which is the point). Cc @Max

> The bigger the transaction, the harder it should be to keep private, which is exactly how bitcoin is structured. That’s not how Bitcoin is structured, but if it was, that would be great. I agree.

It is exactly how it's structured by keeping the base layer transparent. The larger the amount of value you move, the less work is required to determine who moved it. The inverse is also true.
