Sanctions are a different animal. I have no problem with a government producing a court order or other legal instrument ordering that some entity be cut off from the financial system. (Certainly sometimes this is done for political reasons, rather than cases where actual harm is being done, which is unfortunate, but I don't think it's reasonable to expect to be fully able to prevent things like that.)

KYC and AML laws require private corporations to deny people access to essential services for arbitrary reasons, without due process. These laws are garbage.

I don't think anyone is arguing that what is, isn't. They're arguing that it shouldn't be.
