How did the case McCulloch v. Maryland cement the power of the federal government?

In the case of McCulloch v. Maryland, the Supreme Court established that the federal government was the supreme ruling body in the Nation (such as banking). In conclusion, the ruling outlined the federal government's responsibility for legislating and controlling intrastate commerce.

This case cemented the power of the Federal Government by stating that it had the authority to create National Banks and furthermore it denied the right of the states to tax a federal business. This ability allowed for the Federal Government to create additional agencies in the states that could not be directly taxed by the states themselves.
