COMPLETE QUESTION: The Necessary and Proper clause was especially important when it came to: a. Declaring war c. Raising an army b. Regulating commerce d. Coining money.

The "Necessary and Proper" clause can be found in Article I, section, 8, Clause 18. The "Necessary and Proper'' clause is the part of the Constitution that makes or allows or gives the congress the authority to make laws for the proper functioning of the country.

And this is one of the most important part of the power of the Congress to make laws.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
