The whole idea of what is property and what isn't... it's just how a group of people (usually: population of a country) define it (usually: democratically or by decree of some dictator).
If a country decides tomorrow that pencils can not be property anymore, then pencils aren't. It's that simple. What the consequences are I don't know, maybe nobody is going to buy a lot if you can't keep them, but that is separate discussion.
So... the question should be... "Is it desirable for a country to support the concept of IP, yes or no?"
The rest of the questions are moot.
