"because no amendment was enacted giving that power to the federal government in the first place."

Why do you think that we need an amendment giving power in order to pass an amendment taking it away?

The federal government already has the power in Article I, Section 8. If we wish to remove that power, we need a constitutional amendment. Period.

Nope. If that were true, there would have been no Eighteenth Amendment (an ordinary federal statute would have sufficed).
