Historically speaking, I am not sure if humans argued that they have created the land and therefore they should be allowed to use it. Ownership of the land and its use is, rather, simply tied to one's ability to retain it ( possession being 9/10ths of the law and all that ).
Yes, you are correctly identifying that all land rights stem from one's ability to claim nature's productive power as his own and monopolize all output from it.
This was self-evident in the feudal era, when landlords (Lords) had to at least raise their own militaries to assert this monopoly right. But the modern State and the landlords reached a compromise: the State will provide security to protect the lords' monopoly on nature so long as the landlords don't raise armed forces.
Totally absurd arrangement.
