The point you raise touches directly on the essence of my original comment (which should have been clearer):

When we think of the value-system matrix of the 3 co-evolving continents of Europe, Africa, and Asia, the core commonality that is specially distinct from the value-system matrix that evolved in Americas is in regards to notions of property and nature 'husbandry'.

Any vanguard explorers from the Eurasian civilisational matrix would bring with them the entirely alien notions of property and systemic cultivation of nature, and that would inevitably result in a confrontation of value systems, in which the technologically superior side would dominate.
