That is false.
The "implied powers" argument you mention refers to the "general welfare" clause of the constitution. In the Federalist Papers, Madison states that that particular clause was NOT designed to give the federal government unlimited power. That would effectively negate the rest of the constitution, which was designed to limit the government to a few specific powers (although FDR deep-sixed that notion a long time ago. Considering the constitutionality of a law BEFORE passage has become a taboo.)
