Because a corporation is not property, it is a method of organising a business.
For some reason you avoid this.
I didn't avoid it, I ignored it, because it is off topic. Non sequitur
Wrong. Tell that to Bill Gates. Of course stock in a corporation is property.
I can see your difficulty. You apparently don't know what property is.
I would live to agree with your property theories but so far you are unable to explain kust how they manage to describe current reality.
