Our society recognises that intellectual property can be owned.
Hogwash. What person really believes that the fictitious person "time warner" really owns the song happy birthday, and has a legitimate grievance if you sing it? You claim society recognizes that as some kind of legitimate ownership? What person believes that Microsoft will be able to prevent people from using old versions of XP they downloaded? I know they wouldn't want to prevent that, but I think most people realize they couldn't anyway. What portion of society is morally outraged when you photocopy a piece of sheet music for your class?
Society recognizes that we have backwards laws which can from time to time be taken advantage of for personal short-term gain. It is 100% clear that the only way to keep ideas "owned" is to not publish them. Once they are public, claims of ownership are basically ludicrous but sometimes still accepted in corrupt courts.

[]..Because it makes us better off.
Somehow your claim here without any example is not as compelling to me as articles by e.g. the Economist, inventors, musicians, researchers, and a growing chorus of people from all walks of life screaming how so-called IP laws make us MUCH WORSE OFF. Medically, academically, technologically, economically, and ecologically IP laws have been DEVASTATING. Seriously. Don't take my word for it, read about it and think it through.

You keep trying to pretend that this reality can't make sense but it does. Everyone understands it. The system works. You can go anywhere in the world and buy a can of Coca-Cola and you get what you wanted.
You get what you wanted if indeed the bottler put what you expected and what they claimed into the bottle. If not, they committed fraud. This has nothing to do with Intellectual Property. Budweiser of Czech is not committing fraud, they have a product also named "Budweiser" and they tell you it was brewed in the Czech republic. Do you agree with the IP lawyers who don't think that should be legal?

We have a super-abundance of good things based on intellectual property.
You might as well claim that we have a super-abundance of good things because you prayed for them on sunday. The same quality of evidence exists backing up that statement.
In short, if you don't like the concept of intellectual property, come up with something that will produce more goods for us as a society.
OK: here's something. Abolition of IP laws. That would clearly produce more goods for us as a society. The proof is trivial: IP laws explicity prevent production, allowing only one party (the monopoly) to produce in a given area. Opening up production to other parties could only encourage production of goods.
