Defining Property Rights.

1. I paid for it.
2. Legal title.
3. I discovered it.
4. I used it first.

1. We can pay for stolen goods.
2. We can pay for stolen goods that society deems acceptable. Like slaves once were.
3. I can discover something of value on your property. Like a gold watch in your attic you never knew you had.
4. I can intercept something in the post you bought from Amazon and use it first.

1. Taxation of factors produced by human effort.
2. Uncompensated exclusion from scarce natural resources.
3. Exclusion from the ability to use any idea.

I would therefore postulate that if property rights are fundamental, then the fact that every Country in the World is guilty of doing a,b and c, then this is the root cause of much, if not all, social and economic dysfunction.
