You need to watch this video as it explains what is wrong with that statement:

The only area for any debate is establishing a framework for use of raw material resources (land, and the resources on it such as metals/wood/water, etc., which is not the same thing as the idea of "property".)
What you are basically saying is that no one has anything unless "society"
allows it anyway, therefore society can take back what is essentially it's own property at anytime. This is ridiculous. Something does not belong to me merely because no one else has attempted to take it from me.
This may not be how you perceive your position but this is my understanding of your interpretation.
