I'm old enough to appreciate westerns. Yo dig. I was struck by something that conservative commentator David Brooks said during the upheaval of 2020. While discussing the protests sparked by the execution of George Floyd on PBS he said "(F)or many decades, the pioneer experience was the defining American experience. And then the immigrant experience was the defining American experience. 
Now the struggle for racial justice is the defining American experience." He's absolutely right. This here song is a romanticisation of the initial American Experience at the tale end of the European Conquest of the Americas. As a nation we need to talk about this shit. Millions died. Also this is an obvious nod to the "pioneer" of Outlaw Country, the legend known as Hank III.
