Fought over since before most "commodities" existed , and maybe most religions -at many scales from the world, to countries, to a sopt by the river bank, or the comfy chair in the living room - including by various human and non-human species.
Pursuit of economic and political power though control/acquisition of land just has so much glorious and colourful heritage; it's no mere pleb of a commodity .
Something most everyone could use just a little bit more of.
Not everyone could use more cars and tangerines.
cars and tangerines have a generally more competetive market of sustitutes.
Land doesn't really have substitues.
If i could build a house/farm out of tangerines without any land needed, i'd get your point,
