If anything - your arguments actually reinforce the article's point of view because resource heavy areas get pilfered by others and the victors often place or leave extractive institutions in these areas, thus leading to poor economies. Countries that have winters have incentives to colonize resource-rich areas for the reasons you cite. If these resource rich areas have the advantage of having resources... then why is it that these areas are often colonized instead of the other way around?
Also - the article presents these arguments because they're simply sourcing arguments from Daron Acemoglu, who is a labor economist from MIT. Therefore, it will be written from a developmental economics point of view, not from political economics.
>In a just world, Spain, Portugal, the UK, France, the US, and the Benelux countries would collectively be forced to pay reparations amounting to about five to ten trillion euros/pounds/dollars per annum to their ex-colonies, slaves, and exploited peoples until the latter returned to a semblance of development with everyone above the poverty line, and with reliable electricity, sanitation, food supply, housing, and Internet access.
You're not wrong for wanting reparations but this argument has nothing to do with the article at hand.
