Wouldn’t privatization of land result in natural monopolies?
No one owns the atmosphere, so nobody can be able to buy it from anyone. Instead, part of the troposphere is owned by the land owner residing in the crust. But above a “reasonable” height, aeroplanes can fly over it because nobody owns it.
If nobody owns land in the first place, nobody can buy it. Someone has to own the land first in order for private ownership of land to take place. The first entity that owns the land is usually the government. The government then sells the land so private transactions of land can take place.
Does claiming land that nobody owns violate the non-aggression axiom? Does privatization of part of the exosphere that nobody owns violate the non-aggression axiom? Does ownership of land without putting your “labor” into it violate the non-aggression axiom? I think these questions do not have their respective axioms to be proven.
When you buy a piece of land, it may or may not include the air above it. If it includes, how high? They are specified in a contractual agreement. It is called freedom of contract.
When you are polluting bad air to your neighbor, you are creating pollution. How about polluting photons that are representing indecent exposure images? How about polluting radio waves, cell phone waves, sattelite waves, microwaves or x-rays to your neighbor? There isn’t a clear distinction between polluting your neighbor and not polluting your neighbor. Polluting x-rays might hurt your neighbors. Polluting microwaves may hurt some of your neighbors. Of course, you don’t have to build thick walls like the walls of banks. It’s up to the government to make the distinction.
Many economics theorists would instead use an axiomatic abstraction, so they won’t have to deal with these things.
Graphs can be abstraction of private land ownership. Transportation through land is equivalent to traveling through weighted edges on a graph. The weighted edges are equivalent to the price one has to pay to travel through each landowner’s land. The shortest paths can be found using the Bellman-Ford or Dijkstra’s algorithm if there is perfect knowledge of the prices of each landowner.
If Smith’s land is surround around Jones’ land (Is creating boundaries around someone on your own private property wrong?), then Smith would probably let Jones starve to death so Smith can steal Jones’ land after he dies. Jones might instead use his cell phone and get a helicopter to transport him somewhere else. Jones would sell his land while leaving.
But if Smith’s walls are blocking his cell phone waves, Jones has no hope. However, Smith might give Jones an offer: If Jones agree to be Smith’s slave, then Smith would feed him. Jones agrees to be Smith’s slave.
A more realistic case is when your neighbors around you agree to block you. This might happen in a society where there are private roads. Private road companies would block you. They have rational motives to kill you: when you die, you have to pay the estate tax so others would pay less taxes. They could enslave you. They could force you to sell your wealth. They could be “bribed” by road companes to block you, so road companies would get rich from making roads that pass through your neighbors.
The barriers to entry on land is almost impossible. Companies has to buy expensive land to start a business. Internet companies have to buy land to connect wires. Suppose these wires are roads?
Neighboring businesses on land are much more likely to for a cartel or collude you because the barriers to entry are very high. Imagine a business owns all of your adjacent land. They do not face a threat to new firms, so they would block you.
How are you going to survive without public roads? Of course, you can limit the business blocking you by setting a contractual agreement before they build it, but it isn’t your property. Of course, your neighborhood can all agree to a contractual agreement prohibiting blocking, but if some does not want to?
Of course, when building a new community, people can form a cooperative when they move to a new area and together to build a road that can move to other places. However, I am talking to places that already are not surrounded by roads. Does the government have to first use eminant domain to these places?
Does blocking create an protectionist environment where the blocked group create a local maximum?
