I think the Time you're talking about makes all the difference.
10,000 years ago, Grok had no concept of property. If Grok & Tharn dispute this little bit of land, the witch doctor comes along & says "get to hunting, yow great d-bags! What, what!" & they get to hunting. It's irrelevant.
6,000 years ago, Tibus & Timus dispute over a plot of land & they fight. Possibly with their tribes behind them. Winner take all. You... cannot... take.... our.... sweet potatoes!
2,000 years ago, we start to get codified "rights" to land, but it's still Might-Makes-Right, for the most part. Ibrim & Orim both want the same land. They take it to the chief/pharoah/prelate, depending on where they live. If they live in different civilizations, they probably go to war. If they live in the same civilization, they probabaly go to war anyway, but the winner declares the loser as unholy & sacrifices abound. What, what! Not much progress has been made, honestly.
1,000 years ago we have Kings & whatnot. All the known land has been divided, it all belongs to the King, & he grants it to whoever he likes best. You wanna take it? You best have a good army, else the chopping block for you. Still Might Makes Right.
500 years ago, there's a whole unoccupied continent discovered, with the only problem being the people who occupy it. Kill 'em, smallpox 'em, Kevin Costner 'em. Might definitely still makes right.
250 years ago. No taxation without tea. Or something. Wars ensue. Whoever learns that lining up across from your foe & shooting at each other is a bad tactic, wins. Might, maketh thee right, what, what? And then thou get your own country.
200 years ago, all the lines have been drawn on paper & are quite steady, so now we can get down to divvying up our countries tout suite.
Here's where Property Rights come into play. Jethro the gold prospector suddenly needs the government to protect his rights, 'cause he can't do it with his 5 sons & 2 guns. Might Makes Right? That's not fair! Left to his own devices, Horace his next door neighbor wil take his claim by force of arms, & we can't have that because Jethro has friends in high places!
So Jethro enlists the government to declare that he is the rightful owner of his claim, thereby gaining the backing of The Entire United States Government in protecting it. Take that, Horace, you jerk. Horace has all sorts of Might on his side, but he's outta luck, 'cause now we have Property Rights, all legal & such.
Today, one buys a deed of land, with or without a building situated upon it, through a licensed broker, using the Federal Government's interest rate as a benchmark, often financed through an FDIC-backed bank, with the knowledge that the government will both acknowledge you as the owner & protect your right to own, inhabit, & sell that land. All 'cause of Property Rights. Stupid Jethro.
Sure, some may say that's still Might Makes Right, but Grok can still tell Tharn to get off his lawn, so it's all good. That's all Grok wanted to begin with.
