That criminals break laws and crimes require investigation and prosecution which are activities that have associated expenses is not new. You have to remember that both investigation and prosecution involve a large amount of discretion, so the cost of the sanctions regime is dynamic and variable. Enforcement can put a small effort against low-value components and put a large effort into violations of high-value components. If the small effort put against low-value components deters some activity, then the goals of the sanctions regime are furthered.
