The institution of private property is a wholly artificial one, the construction of society, and it therefore reflects no pre-political or pre-social moral truths. In evaluating private property from an ethical point of view, the sole relevant considerations to take into account are the prevailing social attitudes; and if (as is the case) the prevailing social attitudes regard government taxation of earnings as justified, well, then there are no legitimate grounds for complaint about taxation of earnings.
This line of thinking goes back to Rousseau, “The first man who, having enclosed a piece of ground, bethought himself of saying This is mine, and found people simple enough to believe him, was the real founder of civil society. From how many crimes, wars, and murders, from how many horrors and misfortunes might not any one have saved mankind, by pulling up the stakes, or filling up the ditch, and crying to his fellows: Beware of listening to this imposter; you are undone if you once forget that the fruits of the earth belong to us all, and the earth itself to nobody”
The Grounds of the argument is that those portions of man kind that existed without visible states, borders, or permanent properties such as the native indian new nothing of property and thus shared everything. This ideology was successfully challenged by Thomas Woods while dealing with the myth of Indians as “socialistic” Environmentalist. (http://mises.org/daily/2642)
I revert to a quote from that article
“Although we often hear that the Indians knew nothing of private property, their actual views of property varied across time, place, and tribe. When land and game were plentiful, it is not surprising that people exerted little effort in defining and enforcing property rights. But as those things became more scarce, Indians appreciated the value of assigning property rights in (for example) hunting and fishing.”
From reading the above discussion I do feel that no one is attempting to refute property per say, though just how it is acquired; specically objects. Using the example of person A and Person B; While Person B is out for his morning stroll and comes to find a cave. After looking around noticing that no person is habitating the cave decides to make it his base location where he sleeps, eats, and plans his days out, similar to homesteading. Then comes along person A, whether or not person A is passive or aggressive, B has established this property as his. Should person A attempt to aggress in any manner the food, location, or other objects that person b has aquired through no force to other humans, then person be has the option to defend or not defend his propety. The underlying understanding is that it is his property to begin with.
The Premise is that property is obtained by staking the first claim or building it, the fact that one may not be able to defend it does not mean it is just or right for other to take it over. In fact what would be right in such a situation, is for the original owner to reclaim the property once he is able to do so, or its equivilant value. If the original owner never decides to reconquer this property it does not mean it has been morally transfered but rather stolen with no intent of redemption.
