Why can congress print money but cannot issue licenses?

Congress can print money because it is granted the power to regulate currency and manage the nation's monetary system as outlined in the Constitution. This authority is primarily exercised through the U.S. Department of the Treasury and the Federal Reserve System. In contrast, issuing licenses is typically a power reserved for state and local governments, which have the authority to regulate various professions and activities within their jurisdictions. This division of powers reflects the federal structure of the U.S. government, where certain responsibilities are designated to different levels of government.
