There is no natural right to private property. There is only something close to a right to your own labour.
You can make a claim to that spear, of course. It's the product of your labour, you would get to own it, and you made it with freely available resources. One would call this "personal property".
However, imagine this scenario. You and I get marooned on an unclaimed island. I claim the island before you get the opportunity. Because of my claim on this land, which now becomes my private property, I force you to give me that spear.
This is exactly what happened in all of the globe. People laid claim to land, resources and capital that they did not build, and this is precisely the base of all private property beforethen. If I were to get any object I own, I could trace my ownership of that object to someone that, at some point, violently decided that some land is theirs, and based on the idea that the land is theirs seized the product of the labour of various people who had no choice but to work it or die.
So, unless you agree that seizing land that was not yours violently is a reasonable way of generating ownership, you come to the conclusion that the ownership of essentially everything in our society is illegitimate, and can only be motivated for utilitarian reasons.
If you do, then you agree that I have a right to your spear :)
