Please note that when a government purchases goods from retail suppliers today it pays the same taxes levied and embedded in the prices of those goods as everyone else.

Not according to Wisconson tax law. Apparently you read it, yet still don't understand the simple wording.

Sales of goods and services to the federal government or to any of its incorporated or unincorporated agencies or instrumentalities are exempt from the sales tax.

Taxing purchases by the federal government would violate the U.S. Constitution, so the fiscal effect of this exemption has not been estimated.

Which part do you not understand, specifically?

Not according to Wisconson tax law.

Constitution for the United States of America:

• Article VI: "This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding."

Wisconsin tax law, cannot tax federal entities. That has nothing to do with Federal Law taxing Federal entities.
