Lets say I'm on an island.
-Do I "own" this island?
Lets say one day a girl arrives on this island.
- Is it my island still? Is it our island? Do I have more of a right to this island than she does? If it is my island can I kick her off?
Lets say me and this girl have a child.
- Who owns this island now? None of us? All of us? Just me?
Let's say his children have children etc and now 5000 people live on this island.
- Who owns the island now? If anyone owns the island do they have the right to kick the ones that don't off the island?
Lets say instead of just me on this island in the first instance its a group of 1000 people.
- Who owns the island?
Lets say one day 1000 other people show up on this island
- Do the first group own the island? Do they all own the island now?
Isn't the world an "island"?
