I agree it’s complicated, but i guess my point of contention is in the relative nature of scarce in this context. 

Sure, hospitable land is seemingly scarce when compared to inhospitable lands. But relative to the scarcity of bitcoin, I would suggest it is actually quite abundant. 

Whatever unit of land you want to use, it would seem more than 21million humans are able to have a single unit of hospitable land. 

DuckDuckGo AI says there are 11bilion farmable acres of land on earth, and my math suggests that’s enough for 1.375 acres per person. Much more than the .002625 bitcoin available per person.
