The argument presented here is based on complete ignorance of the history of the human race.
Reason #1
The concept of property ownership is not a product of capitalism. This idea is literally as old as the oldest known civilization to keep written records, Mesopotamia.
Concern with property, its preservation, and its use shaped not only the Mesopotamian legal tradition but also economic and social practice, notably the ability to sell and to buy land and to transfer property through marriage and inheritance.
In Mesopotamian culture, property was owned by the state, by the temple, and by private families. Records show a distinction between movable property (material goods) and immovable property (land), and the selling, trading, repossessing, inheriting and transfer of all types of property.
Here is an example of a cuneiform tablet recording an agreement about the division of property.
There is even an equivalent of eminent domain:
When Hammurabi asked, “When is a permanent property ever taken away?” he was referring to the established customary legal principle that land was the permanent property of a family.
Hammurabi was not a capitalist. Babylon was not a capitalist nation.
Capitalism did not "invent legal privileges around property".
Reason #2
Conquest of territory happened long before capitalism ever existed. Colonialism was hardly a new concept.
Genghis Khan was not a capitalist. Alexander the Great was not a capitalist. Julius Caesar was not a capitalist. Napoleon Bonaparte was not a capitalist.
If you require citations for this part of my argument, I suggest you find a basic text on world history at your local library.
Conclusion
I'm not going to address the other "reasons" as they are faulty conclusions drawn from the previously addressed faulty premises.
I am not arguing that these things are right and good. I am arguing that linking them specifically to capitalism represents a desperately uneducated understanding of human society and history. This is such a bad take, it reeks of teenage anarchist and "money is the root of all evil" oversimplification.
