A simple connection links the identity of the land to a useful purpose. Backroom deals and political machinations give the land, instantly, a new identity, independent of its history. This is land laundering.
Exxon -- the former Humble Oil Company -- donates land to Rice University, which in turn offers it to the government: land available, of suddenly impeccable pedigree, located, conveniently enough, in Vice President Johnson's home state of Texas.
With the change of title, rice fields and cattle pastures have instantly become a "campus" of an august institution: an ideal place for the space effort's headquarters. As happens so many other places, the land is scraped clean and given a new identity. The signs go up, the bulldozers and earth movers come out, and the land is made new.
(Of course, the deal does not prevent Exxon from maintaining a 20-acre drilling easement on the space center campus, directly adjacent to the lunar simulation area. Today, the lunar simulation area is gone, but the easement remains.)
