Does that apply to all the tribal culture that lived communally, the sort that existed peacefully for thousands of years
No they didn't. There is no such mythical perfectly peaceful primitive tribal culture.
... before running into the white men who exterminated them to take their property?
But if property rights are subordinate to the betterment of society, taking their property to bring them the benefits of modern society should be a good thing, right? Though I do admit the extermination thing is pretty bad.
Without personal freedoms, property rights are useless.
I wholeheartedly agree with that. I would also add that without individual property rights, personal freedoms are useless. As a trivial example, without property rights, what good would be freedom of the press if you had no right to own the press?
Forgive me if I am misunderstanding you, but you seem to be arguing from extremes. There must be at least some individual property rights, if nothing else, to own the clothes you are wearing. That's what I mean when I say that they are fundamental. I do not believe that property rights are paramount over all other considerations. I believe that reasonable people can disagree over where to draw the line. I tend to fall more towards the individual side of the spectrum, you obviously tend towards the collectivist side. There's plenty of room in the middle to come to an agreement and live amicably.
Spoken like a true communist. Other than life itself, there is no more fundamental right than the right to property.
Spoken like a true Objectivist.
If I sounded that way, it was truly not intentional. Unlike objectivists, I don't try to build a huge immoral self-justification on top of first principles. I just wanted to recognize and point out something that has been obvious to any retard ever since Ug the caveman made a cool club and whacked the first guy who tried to take it away from him.
Property rights, along with the right to defend one's self, family and property are fundamental, but they must also be tempered by moral consideration. It is the balance and tension between individual and social considerations that make for a well functioning society. Extremes to either side of the equation are unproductive and ultimately self-defeating.
If there's no incentive for people to make productive use of capital, the economy stagnates.
The incentive for people to make productive use of capital is the reward / gain they get from doing so. I'm no rabid objectivist or "big-L" libertarian, but that's just fundamental economics.
it's not fair to society to let him keep it for no/low cost when it might be put to better, more productive use for society by someone else.
Spoken like a true communist. Other than life itself, there is no more fundamental right than the right to property. From your comments I get the impression that you are not a property owner or you would not be so cavalier in taxing it away.
Reallocating property from one person to another based on "productive use of capital" for the benefit of society over the rights of the individual is always going to be a negative incentive to productivity. Why acquire property if it can just be taken away (or taxed away) at the whim of some powerful individual or group? Some property taxes are probably inevitable to pay for necessary social services (fire, police, etc.) but those taxes should never be used to penalize for some imagined lack of relative "productivity".
Unfortunately, there are others who agree with your line of reasoning, most notably some US Supreme Court justices. See Kelo v. City of New London for a real world example of the results.
