How does the absence of a “necessary and proper” clause in the constitution limit the power of the state government?

The "Necessary and Proper Clause" is one of the most important clauses of the Constitution of the United States. It is inserted in Article I, Section 8 of the constitutional text, and empowers Congress to carry out all those powers not explicitly enumerated in the Constitution that are necessary and proper for the normal exercise of the enumerated powers. In this way, it expands the powers of Congress, expanding them and giving it a margin of action greater than that of the enumerated powers. These powers that arise from this clause are called implicit powers.

In the absence of this clause, Congress would see its actions limited only to the enumerated powers, with which many of the needs of society could not be resolved through Congress, because it would not have the power to do so.
