"Ownership" for you, and all liars, and thieves, requires a deed, etc., simply because you cannot trust the one you are buying from, nor can he trust you. The Native Americans had no need for such since each tribe recognized the boundaries of the other, and there was no distinct boundaries. Native Americans believed in "Mother Earth" as being "owned" by all.
Yet liars, and thieves, like you, and your god Trump, need "contracts" even though you will ignore them when it is convenient for you. Trump has been sued over 3500 times for his violations of contracts, and fraud, and will not release his tax returns which he is lying about. Yet you do not "need" to see those records before defending him.
However, being the ass you are you only "need" the slightest lie to confirm your racist beliefs.
