That is a fallacy. All bitcoin is non-KYC except to the person who attached their government ID to their bitcoin withdrawal address by using a KYC service. Every business that is trying to filter bitcoin based on whether the person sending it is KYC'd to the addresses they are sending from would require total network surveillance. That may actually happen, where a centralized surveillance provider must be queried to approve of transactions. But any bitcoin in such a scenario is captured. Transacting with such a business will be dealing with the devil that is bent on bringing bitcoin to heel.
