Should the government limit the amount of cash that can be used in a single transaction?

Governments are increasingly capping cash payments to squeeze the "shadow economy" where tax evasion and money laundering thrive. While officials argue that limiting cash forces dirty money into the light, privacy advocates view this as a "war on cash" that strips citizens of anonymity. Proponents argue that only criminals need to move large suitcases of untraceable bills; opponents argue that without cash, you are just one system failure away from having zero purchasing power.
