The federal government has the power to tax and the power to spend. What eventually becomes of the lands, buildings, equipment and other properties it holds?

Well, if we accept the argument you've advanced, the government must hold all such properties for eternity, because you contend that the Constitution doesn't give them them an express power to ever sell what it has acquired.

How did the Government aquire it?

When did it happen that that OUR Government could own anything?

It doesn't compute.
