Great post! I completely agree with your point.
I have been thinking a lot lately about how property ownership should be decided/handled. What voluntary mechanisms can we come up with that allow us to have property rights, but also solve problems such as, someone up-river from you dumping pollution in the water, or people polluting the air in general. Do they have the right to pollute our shared air even though it's being done on their property? What if your neighbor builds a waste treatment plant next to your house. It's his property but it also harms your property (you could argue whether or not it counts because it could be indirect but either way I wouldn't want that to happen). How can we balance our right to our property with the shared rights of water, air, sound, smell, sight, etc.
Also, how do we decide who "owns" the land in general. Originally it was just whoever claimed it first. It seems like we could come up with a better way...
I hope that makes sense and I would love to hear your thoughts on it.
