I'm not sure how to answer your question unless you clarify some points for me.
Are you suggesting crypto is harder to track than cash? Most cryptocurrencies are not anonymous. In fact many of the popular coins/tokens have public ledgers - theoretically meaning money laundering, tax evasion, and terrorist funding would be easier to track and prevent etc
