That argument can't float. The government is supposed to be limited, limited to the enumerated powers authorized in the Constitution.
If the government can assert authority where none is granted, then there is no limit to the power of the government. Thus it would not be a limited government...
Congress has no general police powers. It has police powers limited to its delegated powers. That is why you don’t have a single federal police force instead of state and local police forces. Notice the FBI doesn’t issue speeding tickets.
