Set up a government department with a dozen people and a thousand phone lines distributed around the country and with different telcos. Record every call received. Fine telco $100k for every robocall. Increase fines steeply over time.

Way too complicated. Much easier would be to get a warrant for a trap and trace on the line known to be receiving these calls. Then disconnect the robocall lines.
